Background

As a municipal soldier, the wheel type hydraulic excavator has the characteristics of high road running speed, flexibility, convenience in transition and the like, and the market demand is continuously increased.

The excavator comprises an upper vehicle body and a lower vehicle body which are connected through a slewing bearing, and the upper vehicle body can drive the excavating mechanism to rotate to assist in excavating operation; the running mechanism can drive the lower vehicle body to run, and the whole vehicle is helped to move.

In order to prevent the upper vehicle body from rotating relative to the lower vehicle body when the wheel type hydraulic excavator runs at a high speed, which causes a safety accident, a rotation locking device needs to be designed between the upper vehicle body and the lower vehicle body to ensure that the upper vehicle body and the lower vehicle body do not rotate relative to each other.

At present, the traditional fixing method of the wheel type hydraulic excavator is realized by a lock pin assembly, but the lock pin assembly has the following problems: 1. an operator needs to go out of the cab to insert and pull out the locking bolt, so that the operation is inconvenient in actual work; 2. as most excavators do not have the functions of automatic alignment, deflection angle reading and the like, in order to ensure that the locking bolt can be inserted smoothly, a guide sleeve needs to be aligned with a pin hole by a manual operation machine, and the locking operation efficiency is low; 3. it is desirable to separately design the locking bolt for placement when not in use.

Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example 1:

the embodiment of the invention provides a rotary locking device which is used for locking relative rotation between a rotary part and a fixed part and comprises a limiting mechanism 10, a bolt mechanism 20 and a driving mechanism 30, wherein the bolt mechanism 20 and the limiting mechanism 10 are respectively arranged on the rotary part and the fixed part and are mutually matched to lock the rotary part, and the driving mechanism 30 is arranged on the rotary part and is used for controlling connection and disconnection of the bolt mechanism 10 and the limiting mechanism 20.

Specifically, stop gear 10 and mounting welding, stop gear 10 include limiting plate 11, a spacing section of thick bamboo 12 and deep floor 13, and the rigid coupling is realized through the welding to the three, and 11 upper surfaces of limiting plate and 12 up end parallel and level of a spacing section of thick bamboo.

Specifically, the plug pin mechanism 20 is welded on the rotating member, the plug pin mechanism 20 comprises a sleeve 21, a plug pin 22 and a cover plate 23, the sleeve 21 comprises two axial sliding grooves 25, and the two axial sliding grooves 25 are symmetrically distributed on the sleeve 21; the bolt 22 is provided with two symmetrical radial inserted rods 24, the two radial inserted rods 24 are arranged on the bolt 22 through a bolt structure, the two radial inserted rods 24 are arranged in the two axial sliding grooves 25, and the radial inserted rods 24 can slide up and down along the axial sliding grooves 25; the cover plate 23 is arranged on the top of the sleeve 22, and optionally, a mounting seat is welded on the top of the sleeve 22, and the cover plate 23 is connected to the mounting seat through a bolt structure.

Specifically, the driving mechanism 30 is welded on the rotating member and includes an electric push rod 31, the electric push rod 31 includes a pushing member 32 and a toggling member 33, and the toggling member 33 is connected with the pushing member 32 through a pin.

When the relative position of the rotating part and the fixing part is not required to be fixed by the rotating locking device, the pushing part 32 of the electric push rod 31 is in a completely extended state, the pushing part 32 pushes the toggle part 33 to be in the highest position, and the toggle part 33 pushes the radial insertion rod 24 to enable the bolt 22 to do contraction motion relative to the sleeve 21, so that the bolt 22 is ensured to be in the highest position; at this time, the latch mechanism 20 is in an unconnected state with the limiting mechanism 10 under the action of the driving mechanism 30, and the rotating member and the fixed member can rotate relatively.

When the relative position of the rotating part and the fixed part needs to be fixed by the rotating locking device, the driving mechanism 30 is given an electric signal to control the pushing part 32 of the electric push rod 31 to be completely retracted, the toggle part 33 descends to the lowest position, the supporting function of the toggle part 33 is lost, and the bolt 22 does extending movement relative to the sleeve 21 under the action of self gravity;

if the rotating part and the fixing part are in an aligned state, the limiting cylinder 12 is coaxial with the sleeve 21, and the bolt 22 falls into the limiting cylinder 12, so that the rotating part and the fixing part are locked;

if the position of rotating member and mounting has the deviation, spacing section of thick bamboo 12 is not coaxial with sleeve 21, and bolt 22 bottom surface falls on 11 up end of limiting plate, and operating personnel need correct the automobile body through the small-angle this moment, corrects the in-process, and bolt 22 bottom surface slides until falling into spacing section of thick bamboo 22 along 11 upper surfaces of limiting plate to the realization is to the locking of rotating member and mounting.

When the locking is required to be released, the driving mechanism 30 is given an electric signal to control the pushing part 32 of the electric push rod 31 to be completely extended, the poking part 33 pushes the bolt 22 to be lifted to the highest position, the bolt mechanism 20 is disconnected with the limiting mechanism 11, and the rotating part and the fixing part can rotate relatively.

Example 2:

the difference between this embodiment and embodiment 1 is that a spring 26 is disposed between the latch 22 and the cover plate 23, one end of the spring 26 abuts against the upper end surface of the latch assembly 22, and the other end abuts against the lower surface of the cover plate 23, and when the rotary locking device needs to fix the relative position of the rotary member and the fixing member, the latch 22 makes an extending movement relative to the sleeve 21 under the action of its own gravity and the spring force.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
