Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A squeegee machine and a squeegee tensioning device used for the same according to an embodiment of the invention are described below with reference to the drawings.

Fig. 1 is a schematic structural view of a blade tensioning device for a scraper machine according to an embodiment of the present application. As shown in fig. 1 and 2, a blade tension device 100 for a scraper machine according to an embodiment of the present application includes: a squeegee latch assembly 10, a tensioning mechanism 20, and a control unit 30.

The number of the scraper clamping assemblies 10 is two, the scraper clamping assemblies 10 are used for being connected with scrapers in a scraper conveyor, two ends of each tensioning mechanism 20 are respectively provided with one scraper clamping assembly 10, the control unit 30 is connected with the tensioning mechanisms 20, and the control unit 30 is used for controlling the tensioning mechanisms 20 to provide tensioning force for the two scraper clamping assemblies 10 so that the distance between the two scrapers connected by the scraper clamping assemblies 10 is reduced.

That is to say, when the scraper tensioning device 100 is used for work, the two scraper clamping assemblies 10 are respectively connected with the two scrapers near the failure point, and the control unit 30 controls the tensioning mechanism 20 to contract so as to provide tensioning force to the two scraper clamping assemblies 10, so that the two scraper clamping assemblies 10 are under the action of the tensioning force to drive the two scrapers to move, and the distance between the two scrapers connected by the scraper clamping assemblies 10 is reduced.

From this, the tensioning device of scraper blade for scraping trigger that this application provided exerts the tension through the control unit control straining device to scraper blade joint subassembly, can effectively improve the taut degree of automation of scraper blade in the scraper blade chain maintenance process, reduces artificial participation, improves maintenance efficiency.

Optionally, the scraper clamping assembly 10 is a clamp type manipulator, that is, each scraper clamping assembly 10 can be wrapped by at least two finger structures, and a space for accommodating a scraper is formed between the two finger structures, so that the scraper clamping assembly 10 is connected with a scraper through close fitting of the two finger structures.

Further, the squeegee snap assembly 10 can also include bolts for fastening the robot.

Specifically, because scraper blade structure is great among the scraper blade machine, only adopt the finger structure of clamp formula manipulator to step up the scraper blade, produce the pine easily in taut process and take off, produce danger to maintenance personal, consequently, can be provided with at the distal end of manipulator and be used for fastening connecting bolt with two finger structures, and then effectively prevent taut in-process scraper blade pine and take off, ensure the security at straining device.

Optionally, the tensioning means 20 is connected to the power means of the tail tensioning device of the scraper.

It should be noted that, scrape the trigger and starting, the operation, the brake light in-process, the scraper blade chance is because of the motor starts the impact force that produces and is stricken the scraper chain fast, make the scraper chain produce the creep, lead to scraping the flaccid unable work etc. of scraper chain, consequently, relevant technique can set up straining device at the tail of scraping the trigger usually, in order to ensure to scrape the scraper chain perpendicular to head pulley and tailwheel all the time, guarantee that they have certain tensile force, difficult emergence leads to falling the chain because of being taut tailwheel off tracking, chain breakage, phenomenons such as disconnected scraper blade. And when scraping the trigger and breaking down, need maintain the scraper chain, then need not to use tail straining device, consequently, can use tail straining device to provide power for straining mechanism 20 to effective reduction in production cost reduces the complexity of scraping trigger structure.

Further, the tensioning mechanism 20 may be a hydraulic ram or an electric ram.

That is, when the tail tensioning device adopts the hydraulic pump station to provide power, the tensioning mechanism 20 can be a hydraulic oil cylinder, and an oil inlet and return pipe of the hydraulic oil cylinder is connected to the hydraulic pump station to form a hydraulic loop; when the tail tensioning device adopts the motor to provide power, the tensioning mechanism can be an electric push rod, and a power supply loop of the electric push rod is connected in parallel with a power supply loop of the motor to form a power utilization loop.

According to an embodiment of the present application, the blade tensioning device 100 for a scraper further comprises: the scraper chain sensor is arranged on the tensioning device.

The scraper chain sensor is connected with the control unit 30, and the control unit 30 is used for receiving the scraper chain state detected by the scraper chain sensor, controlling the tensioning mechanism 20 to provide tensioning force for the scraper clamping assembly 10 when the scraper chain is in an abnormal state, and controlling the tail tensioning device to stop operating when the scraper chain is in the abnormal state.

It should be noted that the scraper chain sensor may be a pressure sensor, and the control unit 30 determines that the scraper chain is in an abnormal state when the pressure detected by the scraper chain sensor is smaller than a preset threshold value.

It should be understood that, because the tail tensioning device can continuously provide tension for the scraper chain in the operation process of the scraper, a pressure sensor can be arranged on the tail tensioning device, and the pressure sensor is used for detecting the pressure in the tensioning state of the scraper chain, if the pressure detected by the pressure sensor is greater than or equal to a preset threshold value, the scraper chain is in the tensioning state, namely, in a normal working state, and if the pressure detected by the pressure sensor is less than the preset pressure, the scraper chain loses the tension, namely, the scraper chain is abnormal, and at this moment, the scraper chain needs to be maintained.

Specifically, need first through the artificial detection scraper chain abnormal point, then link to each other two scraper blades of two scraper blade joint subassemblies 10 and either side of abnormal point, then the control unit straining device 20 provides the tension for scraper blade joint subassembly 10, make the scraper blade of the opposite side kept away from to the scraper blade of abnormal point one side, in order to provide bigger space and make things convenient for the maintenance personal to maintain the scraper chain, and simultaneously, control unit 30 still controls tail straining device shut down so as to prevent to make the abnormal point skew to take place under tail straining device's effect, influence the maintenance personal operation, energy saving simultaneously.

In conclusion, according to the scraper tensioning device for the scraper conveyor, which is provided by the application, the tensioning mechanism is controlled by the control unit to apply tensioning force to the scraper clamping component, so that the degree of automation of tensioning of the scraper in the maintenance process of the scraper chain can be effectively improved, the artificial participation is reduced, and the maintenance efficiency is improved.

In order to realize the above-mentioned embodiments, the present application also discloses a scraper, as shown in fig. 2, the scraper 1000 includes a scraper tensioning device 100 for the scraper.
