Description

Technical Field

[0001] The utility model relates to a rear locking mechanism for a rear baffle of a tamping coal charging vehicle, belonging to the technical field of tamping coal charging vehicles. Background Art

[0002] At present, the rear locking of the existing tamping coal-charging car is mainly achieved by squeezing the friction plate through a hydraulic cylinder, and the friction and pressure of the friction plate are used to achieve the locking of the rear baffle and the anti-retraction seat, which is used to prevent the rear baffle from tipping over when the tamping coal-charging car is tamping. However, this structure is prone to locking failure, and the hydraulic cylinder requires regular inspection and maintenance, and the operating cost is also high. Utility Model Content

[0003] In order to solve the technical problems existing in the prior art, the utility model provides a rear locking mechanism for the tailgate of a tamping coal charging car which has a simple structure, a reasonable design, adopts a purely mechanical structure, operates reliably and stably, and has a low cost.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is a rear locking mechanism for the tailgate of a tamping coal-loading car, comprising a locking hook installed on a recoil stop seat and a fixing frame installed on one side of the recoil stop seat, a spring pressure wheel installed on the fixing frame, an articulated seat installed on the recoil stop seat, the locking hook is hingedly installed on the articulated seat, the front end hook of the locking hook is used to hook on the hook plate of the tailgate under the pressure of the spring pressure wheel, the locking hook and the articulated seat are eccentrically arranged, and the front end weight of the locking hook is less than the rear end weight of the locking hook.

[0005] Preferably, the spring pressure wheel includes a mounting tube, a lifting rod, a spring and a roller. The mounting tube is installed on a fixing frame through a connecting seat. A fixing plate is installed in the mounting tube, and a top plate is installed on the top. Both the fixing plate and the top plate are provided with through holes. The lifting rod is located in the through hole. A roller is installed at the bottom of the lifting rod, and a fixing nut is installed on the top. A spring is installed between the fixing plate and the top plate, and the spring is sleeved on the lifting rod.

[0006] Preferably, a control panel is mounted on the lifting rod, a guide rod is mounted on the control panel, a guide hole is provided on the connecting seat, and the guide rod is located in the through hole.

[0007] Compared with the existing technology, the utility model has the following technical effects: the utility model has a simple structure, a reasonable design, and adopts a purely mechanical structure. Compared with the previous cylinder locking structure, it reduces the cylinder and hydraulic system, realizes a maintenance-free design, and the structure runs more stably and has lower operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural diagram of the present utility model.

[0009] Figure 2 It is a structural schematic diagram of the utility model when locked.

[0010] Figure 3 for Figure 1 A partial enlarged view of point A in the middle. DETAILED DESCRIPTION

[0011] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0012] like Figures 1 to 3 As shown, a rear locking mechanism for the tailgate of a tamping coal-charging car comprises a locking hook 2 mounted on a recoil stop seat 1 and a fixing frame 3 mounted on one side of the recoil stop seat 1, a spring pressure wheel 4 is mounted on the fixing frame 3, an articulated seat 5 is mounted on the recoil stop seat 1, the locking hook 2 is hingedly mounted on the articulated seat 5, the front end hook of the locking hook 2 is used to hook on the hook plate of the tailgate under the pressure of the spring pressure wheel 4, the locking hook 2 and the articulated seat 5 are eccentrically arranged, and the front end weight of the locking hook 2 is less than the rear end weight of the locking hook 2.

[0013] The utility model adopts a purely mechanical structure to replace the existing hydraulic structure. When the tailgate mechanism retracts to the stop seat 1, the spring pressure wheel 4 contacts the locking hook 2. The spring pressure wheel 4 controls the locking hook 2 to rotate around the hinge seat 5, so that the locking hook 2 is hooked on the hook plate of the tailgate mechanism to achieve locking. No manual operation is required, and it is more convenient to use.

[0014] The spring pressure wheel 4 includes a mounting tube 6, a lifting rod 7, a spring 8, and a roller 9. The mounting tube 6 is mounted on the fixed frame 3 via a connecting seat 10. A fixing plate 11 is mounted inside the mounting tube 6, and a top plate 12 is mounted on the top. Both the fixing plate 11 and the top plate 12 are provided with through holes. The lifting rod 7 is located within the through holes. The roller 9 is mounted at the bottom of the lifting rod 7, and a fixing nut 13 is mounted on the top. A spring 8 is mounted between the fixing plate 11 and the top plate 12, and the spring 8 is sleeved on the lifting rod 7. The spring pressure wheel 4 uses the spring 8 to control the up and down movement of the roller 9. A control plate 14 is also mounted on the lifting rod 7, and a guide rod 15 is mounted on the control plate 14. A guide hole is provided on the connecting seat 10, and the guide rod 15 is located within the through hole. The guide rod 15 can cooperate with the lifting rod 7 to control the direction of the roller 9 to prevent the roller from deflecting.

[0015] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
