Abstract
The utility model discloses a kind of digger revolving locking system, relate to construction machinery production technical field; Comprise lock pin assembly, the lock body of described lock pin assembly is fixed on by gripper shoe on the upper cover plate of chassis assembly, and the cotter way of described lock pin assembly is fixed under the main floor of revolving dial assembly; Described lock body includes the lock pin being contained in locking pin seat, and when one end of described lock pin is stretched out from the upper surface of described locking pin seat and stretches in described cotter way, described lock pin assembly is in the lock state; The utility model can solve the hole of need opening in driver's cabin bottom existing in prior art and cause that driver's license noise is large, lock pin automatically slides and causes potential safety hazard, lock pin to deposit separately the problem that may lose under Action of Gravity Field.
Description
Technical field
The utility model relates to construction machinery production technical field, and especially a kind of being arranged between wheel excavator revolving dial assembly and chassis assembly, for the locking system that prevents that revolving dial from rotating relative to chassis assembly.
Background technology
As shown in Figure 1, wheel excavator is comprised of parts such as driver's cabin 11, revolving dial assembly 12, chassis assembly 14, the pivoting support 15 that is located at chassis assembly below and equipments, on Qi highway, travel or during handling weight, in order to prevent that revolving dial assembly from rotating because of accidental cause, collide vehicle, pedestrian or other object around and cause security incident, need between the revolving dial assembly of wheel excavator and chassis assembly, install revolution locking system 13 additional, revolving dial assembly can not be rotated relative to chassis assembly.
At present, the structure of revolution lockable mechanism is on revolving dial assembly, to design a pin-and-hole substantially, in chassis assembly, design a lock pin, lock pin is arranged in cotter way, thereby lock pin is injected while needing to pin-and-hole, revolving dial assembly is pinned, utilize chassis assembly to limit the gyration of revolving dial assembly.
Existing revolution lockable mechanism roughly has following three kinds of structures: 1) pin-and-hole is through cab floor, lock pin is packaged in pin-and-hole, while needing, by being located at pull bar in driver's cabin, lock pin is passed down through to pin-and-hole is inserted in the lock groove that is located at chassis and realizes locking, this structure is because opening hole in driver's cabin bottom, dust etc. easily enter driver's cabin through through hole and pollute, the noise of motor also can import the noise that driver's cabin increases driver's cabin into by through hole simultaneously, therefore higher to the requirement of shelter of through hole, and lock pin likely slides voluntarily under Action of Gravity Field, now operate revolving dial assembly and may damage rotary motor or revolution lockable mechanism, 2) lockpin hole is not through driver's cabin, and lock pin is packaged in pin-and-hole, and the locking of controlling lock pin by the handle on lock pin moves, this structure need to not opened hole and avoid the shortcoming of the first structure at driver's cabin, but needs two people coordinate complete operation, operates comparatively loaded down with trivial detailsly, and lock pin also likely automatically slides under Action of Gravity Field, causes potential safety hazard, 3) lockpin hole is not through driver's cabin, and lock pin is deposited separately, during locking, lock pin inserted to lockpin hole and lock pin groove, also needs two people to coordinate during operation, because lock pin is to deposit separately, do not have the risk automatically sliding, but has the possibility of loss.
Summary of the invention
The purpose of this utility model is to provide a kind of digger revolving locking system, and it can solve that prior art revolution locking system exists need open in driver's cabin bottom hole and cause that driver's license noise is large, lock pin automatically slides and causes potential safety hazard, lock pin to deposit separately the problem that may lose under Action of Gravity Field.
In order to address the above problem, the technical solution adopted in the utility model is:
A digger revolving locking system, comprises lock pin assembly, and the lock body of described lock pin assembly is fixed on by gripper shoe on the upper cover plate of chassis assembly, and the cotter way of described lock pin assembly is fixed under the main floor of revolving dial assembly; Described lock body includes the lock pin being contained in locking pin seat, and when one end of described lock pin is stretched out from the upper surface of described locking pin seat and stretches in described cotter way, described lock pin assembly is in the lock state.
Further: described locking pin seat is tubular body, the sidewall of described locking pin seat has the continuous groove for the handle operation of described lock pin, the described groove left side is vertical elongated slot, and the right is vertical short groove, between described elongated slot and described short groove, by a horizontally disposed groove, is communicated with.
Further: described lock pin is cylinder, described cotter way is tubular body.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, lockpin ventilating is crossed handle and is encapsulated in locking pin seat, is difficult for losing;
2, lock pin is placed in the groove hole of locking pin seat, can be because of Action of Gravity Field automatic locking platform;
3, whole revolution locking system volume is little, manufactures simply, and practical reliable, cost is low.

Fig. 2 is the utility model tomograph.
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is the utility model lock seat and gripper shoe three-dimensional structure schematic diagram.
Fig. 5 is the utility model lock three-dimensional structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described: as shown in Fig. 2 ~ 5,
A digger revolving locking system, is comprised of the main floor 1 of revolving dial assembly 12, the upper cover plate 2 of chassis assembly 14, gripper shoe 3, handle 4, cotter way 5, lock pin 6 and locking pin seat 7, wherein, after gripper shoe 3 welds together with locking pin seat 7, be weldingly fixed on again the upper plane of upper cover plate 2, the sidewall of locking pin seat 7 has groove, this groove is asymmetric gantry shape, the groove on the left side is than the length on the right, between left side groove and the right groove, by a horizontal groove, be communicated with, whole groove is for handle 4 operations that are arranged on lock pin 6 bottoms, handle 4 is connected with lock pin 6 by screw thread, during installation, first lock pin 6 is put into the endoporus of locking pin seat 7, again handle 4 is screwed into the lower thread hole of lock pin 6, locked groove 5 is round tube shape, be welded on the lower plane of main floor 1, locked groove 5 is coaxial with locking pin seat 7.
In the time of need to be by revolving dial locking, first adjusting revolving dial assembly 12 makes its locked groove 5 aim at the center of the locking pin seat 7 on the upper cover plate 2 of chassis assembly 14, make the axle center of locked groove 5 endoporus and the axis coinciding of locking pin seat 7 endoporus, now, stand in the following people of excavator and along groove, stir the handle 4 of lock pin 6, until in the short groove of handle 4 in groove the right, now, lock pin 6 rises and inserts locked groove 5, thereby revolving dial assembly 12 is pinned.In the time of need to be by 12 release of revolving dial assembly, only handle 4 need be pulled back to the straight trough bottom on the left side, now lock pin 6 is got back in locking pin seat 7, and revolving dial assembly 12 is just untied like this.
Implement the utility model, lock pin 6 can be under the effect of gravity automatic locking platform, eliminate the potential safety hazard of prior art, simultaneously because lock pin 6 is encapsulated in locking pin seat 7, eliminated prior art and deposited separately the possibility that has loss because of lock pin 6.
