Disclosure of Invention

In view of the shortcomings of the prior art, one of the objectives of the present invention is to provide an electric hoist with convenient heat dissipation, which has the advantage of reducing the heat generated in the control box from accumulating in the control box.

The above object of the present invention is achieved by the following technical solutions: the utility model provides an electric block convenient to heat dissipation, includes electronic dolly, calabash body and control box, install the electric elements of control calabash body operation in the control box, still include water cooling plant, water cooling plant includes water storage tank, first water pump and two water-cooled tubes that extend from the water storage tank, the cooling water has been stored in the water storage tank, and two water-cooled tubes are connected respectively on the both ends of first water pump, and partial water-cooled tube is in the control box, and partial water-cooled tube is outside being in the control box, sets up the through-hole that a plurality of water supply cold tubes pass through on the control box, all installs the sealing washer on every through-hole, be equipped with the actuating mechanism of the operation of the first water pump of drive on the electronic.

Through adopting above-mentioned technical scheme, when calabash body work, the electric elements work and the production of heat in the control box, the operation of actuating mechanism drive first water pump, make the cooling water in the water-cooling pipe obtain the drive and constantly at water-cooling pipe and water storage tank internal circulation flow, the partial heat in the control box can be absorbed and heat transfer to the external world when the control box is outer to the flowing cooling water when passing the control box, thereby make the cooling water can help the control box portion to dispel the heat continuously, the rate of rise of temperature in the messenger control box obtains controlling.

The present invention in a preferred example may be further configured to: the electric trolley comprises a first mounting plate and a second mounting plate, a first motor is mounted on the first mounting plate, a control box is mounted on the second mounting plate, a bolt is connected between the first mounting plate and the second mounting plate, the side face, opposite to the first mounting plate and the second mounting plate, of the first mounting plate and the second mounting plate are respectively connected with a driving wheel and a driven wheel in a rotating mode, and a driving mechanism drives the driving wheel to rotate simultaneously.

Through adopting above-mentioned technical scheme, control box and first motor are installed respectively on first mounting panel and second mounting panel, maintain the balance of the weight of electric trolley both sides as far as possible, make more stable that electric trolley can remove, and electric trolley can also drive water cooling plant at the removal in-process, increase the radiating time to the control box.

The present invention in a preferred example may be further configured to: the driving mechanism comprises a first motor, a first speed reducer, a first transmission assembly and a transmission gear, the first speed reducer comprises a sealing shell, a reduction gear and a main shaft, the reduction gear is located in the sealing shell, the main shaft is coaxially connected with the reduction gear, the output shaft of the first motor penetrates into the sealing shell and is meshed with the reduction gear, the main shaft of the first speed reducer is meshed with the transmission gear, the transmission gear is coaxially connected with a driving wheel, and the output shaft of the first motor drives a first water pump to operate through the first transmission assembly.

Through adopting above-mentioned technical scheme, first motor provides the electric energy for the removal of electronic dolly and the operation of first water pump respectively, reduces the setting of extra power, reduces use cost to reduce electric block's whole quality.

The present invention in a preferred example may be further configured to: first drive assembly includes first transfer line, first bevel gear and second bevel gear, first bevel gear and the output shaft coaxial coupling of first motor, second bevel gear and first transfer line coaxial coupling, first bevel gear and second bevel gear intermeshing are connected, impeller coaxial coupling in first transfer line and the first water pump.

Through adopting above-mentioned technical scheme, lengthen the distance between first water pump and the first motor output shaft with the help of first transfer line, in case the condition that leaks appears at the operation in-process in first water pump, the work of first motor is also difficult to be influenced to the cooling water that leaks, reduces the influence to the operation of electronic dolly.

The present invention in a preferred example may be further configured to: the first bevel gear and the second bevel gear are both positioned in the sealed shell, the first transmission rod is rotatably connected to the sealed shell through a bearing, and the transmission gear is also positioned in the sealed shell.

By adopting the technical scheme, the first bevel gear and the second bevel gear are protected by the sealing shell, so that the possibility that dust is attached to the contact surface between the first bevel gear and the second bevel gear is reduced; similarly, the sealing shell also plays a corresponding protection role for the transmission gear, so that the meshing connection between the transmission gear and the main shaft is not easy to be blocked by dust.

The present invention in a preferred example may be further configured to: the water cooling pipe penetrates through the sealing shell through the through hole in the sealing shell.

Through adopting above-mentioned technical scheme, the water-cooling pipe still can dispel the heat to the heat that produces in the seal shell when dispelling the heat to the control box, because there is certain interval between control box and the seal shell, the cooling water in the water-cooling pipe can have sufficient flowing distance and the external world carries out the heat exchange, consequently dispels the heat in control box and the seal shell simultaneously and can not weaken respective radiating effect.

The present invention in a preferred example may be further configured to: the calabash body includes the sprocket, installs second reduction gear and the second motor in sprocket one side, the output shaft of second motor stretches out and installs the second drive assembly to one side of keeping away from the second reduction gear, still include the second water pump on the water cooling plant, the second water pump passes through the water-cooled tube and realizes establishing ties with first water pump, the second motor passes through the rotation of second drive assembly control second water pump.

Through adopting above-mentioned technical scheme, when calabash body lifts by crane article, electronic dolly can stop to remove, and first water pump can't move in operation, is rotated by second motor drive second water pump this moment, makes the cooling water enough continue the circulation flow, keeps carrying out the water-cooling to the control box.
