Description

Technical Field

[0001] This utility model belongs to the field of mobile crushing equipment, and relates to a mobile platform support leg that adapts to ground flatness differences, and also relates to a mobile platform that adapts to ground flatness differences. Background Technology

[0002] In the field of mobile crushing equipment, the outriggers of mobile crushing plants are key supporting components that ensure the stable operation of the equipment, and their performance directly affects the safety and efficiency of the equipment operation. Currently, the outriggers of mobile crushing plants commonly found on the market are mainly divided into two types: two-piece type and hydraulic type.

[0003] Two-piece outriggers typically consist of two parts, upper and lower, and have a relatively simple structure, but they have obvious drawbacks. They occupy a large amount of space, which can cause many inconveniences for operators in narrow work areas or during equipment transportation, and limit the flexibility and applicability of the equipment.

[0004] While hydraulic outriggers can achieve a certain degree of automatic leveling, they require extremely flat ground. In actual operating environments, the ground often has uneven surfaces and slopes, making the overall leveling of the equipment extremely complex, time-consuming, labor-intensive, and increasing the difficulty of operation. More importantly, if the outriggers do not make proper contact with the ground, vibrations and load changes during equipment operation can easily cause the equipment to sway or tilt, leading to safety accidents and posing a serious threat to personnel safety and the equipment itself. Therefore, developing a mobile crushing plant outrigger with superior performance is urgently needed. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile platform outrigger and mobile platform that can adapt to different ground flatness, so as to solve the problems of large space occupation, inconvenient operation and complex, time-consuming and labor-intensive leveling of existing mobile crushing station outriggers, which are mainly two-piece or hydraulic.

[0006] The first technical solution adopted by this utility model is a mobile platform support leg that adapts to ground flatness differences, including an outer sleeve, an inner sleeve, a telescopic cylinder and two pins. The outer sleeve is sleeved on the outside of the inner sleeve and the two are slidably connected. The telescopic cylinder is disposed in the cavity between the outer sleeve and the inner sleeve. The top end of the telescopic cylinder is hinged to the top of the outer sleeve and the bottom end of the telescopic cylinder is hinged to the bottom of the inner sleeve.

[0007] Two first adjustment holes are symmetrically opened on the surface of the outer sleeve, and two second adjustment holes are symmetrically opened on the surface of the inner sleeve. The first adjustment holes and the second adjustment holes coincide, and the front end of the pin is inserted into the area where the second adjustment hole and the first adjustment hole coincide.

[0008] Another technical solution adopted by this utility model is a mobile platform that adapts to differences in ground flatness, wherein at least three of the above-mentioned mobile platform legs are installed at the bottom of the mobile platform.

[0009] The features of this utility model also include:

[0010] Furthermore, it also includes a screw, and the pin is divided into pin I and pin II. The front end of the screw passes through pin II and is rotatably connected to the side wall of pin I. The rear end of the screw is screwed with a lock nut.

[0011] Furthermore, a handle is provided at the rear end of the screw.

[0012] Furthermore, a pin locking plate is rotatably connected to the rear end side wall of pin I, and a limit post is fixedly connected to the rear end of pin II. The pin locking plate has an inclined groove, and the limit post slides into the bottom of the inclined groove.

[0013] Furthermore, both the outer sleeve and the inner sleeve are cuboids.

[0014] Furthermore, the first adjustment hole is located on the front and rear sides of the outer sleeve, and the second adjustment hole is located on the front and rear sides of the inner sleeve.

[0015] Furthermore, the first adjustment holes on the front and rear sides are in the same position, and the first adjustment hole and the second adjustment hole on the same side are mirror-symmetrical.

[0016] Furthermore, the first adjustment hole is a strip-shaped hole, and the lower end of the first adjustment hole is inclined towards the axis of symmetry. The second adjustment hole has the same shape and size as the first adjustment hole.

[0017] Furthermore, the front end of the pin passes through the front and rear sides of the outer sleeve and the inner sleeve in sequence, and a pin hole is radially opened on the front side wall, with a cotter pin installed in the pin hole.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses a telescopic cylinder to push the inner sleeve to slide inside the outer sleeve 1. With the overlap of the first and second adjustment holes and the insertion and fixing of the pin, the outriggers can flexibly adjust their height within a certain range, effectively adapting to different ground heights and ensuring that the mobile platform can maintain a relatively stable state even on uneven ground.

[0020] 2. The first adjustment hole is designed as a rectangular hole, with a width at least one-third of its length, and its lower end inclined at 45~75° towards the axis of symmetry. This design can effectively distribute stress, ensuring the structural strength of the outer sleeve, and also allows for selection of appropriate tilt angles according to different application scenarios, enhancing the height adjustment capability and the fixing effect of the pin. At the same time, the cooperation of components such as the screw and locking nut further restricts the axial and lateral movement of the pin, ensuring the stability and reliability of the outrigger structure.

Detailed Implementation

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 The present invention will be described in detail with reference to specific embodiments:

[0032] A mobile platform outrigger that adapts to ground flatness differences, reference Figures 1-7It includes an outer sleeve 1, an inner sleeve 2, a telescopic cylinder 3, and two pins. The outer sleeve 1 is sleeved on the outside of the inner sleeve 2 and the two are slidably connected. The telescopic cylinder 3 is set in the cavity between the outer sleeve 1 and the inner sleeve 2. The top end of the telescopic cylinder 3 is hinged to the top of the outer sleeve 1, and the bottom end of the telescopic cylinder 3 is hinged to the bottom of the inner sleeve 2. The inner sleeve 2 can slide inside the outer sleeve 1 under the action of the telescopic cylinder 3.

[0033] Two first adjustment holes 101 are symmetrically formed on the surface of the outer sleeve 1, and two second adjustment holes 201 are symmetrically formed on the surface of the inner sleeve 2. Specifically, the outer sleeve 1 and the inner sleeve 2 are cuboid structures with identical dimensions. The first adjustment holes 101 are located on the front and rear sides of the outer sleeve 1, and their positions are the same. The first adjustment holes 101 are strip-shaped holes, specifically rectangular holes, with the width being at least one-third of the length. Rectangular holes provide structural stability and prevent stress concentration issues caused by irregular hole shapes. When the outriggers bear the weight of the platform and external loads, the rectangular holes effectively disperse stress, ensuring the structural strength of the outer sleeves and extending the service life of the outriggers.

[0034] The lower end of the first adjustment hole 101 is inclined towards the axis of symmetry, with an inclination angle of 45° to 75°. This inclination angle range covers a variety of different application scenarios. In actual use, a suitable inclination angle design can be selected according to the working environment and ground conditions of the mobile platform.

[0035] The 45° tilt angle ensures that the force distribution is relatively uniform when the pin is under load, reducing stress concentration at the edge of the adjustment hole.

[0036] The 75° angle allows for a wider range of vertical adjustment for the first adjustment hole. When the mobile platform encounters significant ground height differences, this design enables the outriggers to make greater height adjustments, ensuring the platform remains level.

[0037] The second adjustment hole 201 is opened on the front and rear sides of the inner sleeve 2. The first adjustment hole 101 and the second adjustment hole 201 on the same side are mirror symmetrical. The second adjustment hole 201 and the first adjustment hole 101 have the same shape and size. The first adjustment hole 101 and the second adjustment hole 201 overlap. The front end of the pin is inserted into the overlapping area of ​​the second adjustment hole 201 and the first adjustment hole 101. Specifically, the overlapping area is a square. The pin can be designed as a cuboid structure with a square cross-section, which is the same size as the overlapping area. This design allows the side wall of the pin to fit tightly with the overlapping area.

[0038] When the inner sleeve 2 slides inside the outer sleeve 1, the first adjustment hole 101 and the second adjustment hole 201 will overlap. At this time, the front end of the pin is inserted into the overlapping area of ​​the second adjustment hole 201 and the first adjustment hole 101. Through the cooperation of the pin and the adjustment hole, the inner sleeve 2 and the outer sleeve 1 are fixed in the adjusted relative position, thereby ensuring that the outriggers can stably support the mobile platform after the height is adjusted. This adjustment method allows the outriggers to flexibly adjust their height within a certain range to adapt to different ground heights, ensuring that the mobile platform remains relatively stable even on uneven ground.

[0039] The front end of the pin passes sequentially through the front and rear sides of the outer sleeve 1 and the inner sleeve 2. A pin hole is radially opened on the front side wall, and a cotter pin 9 is installed inside the pin hole. During equipment operation, due to factors such as vibration and load changes, the pin may be subjected to axial force, posing a risk of dislodging from the adjustment hole. The cotter pin 9, installed in the pin hole at the front end of the pin, effectively prevents axial movement of the pin due to its unique structure.

[0040] The mobile platform support leg also includes a screw 6. The pin is divided into pin I 4 and pin II 5. The front end of the screw 6 passes through pin II 5 and is rotatably connected to the side wall of pin I 4. The rear end of the screw 6 is screwed with a locking nut 8. Specifically, the front end of the screw 6 passes through pin II 5, and pin II 5 is slidably connected to the screw 6. Pin II 5 can slide along the screw 6. A bearing is installed at the front end of the screw 6, and it is rotatably connected to the side wall of pin I 4 through the bearing. The front end of the pin is inserted into the overlapping area of ​​the adjustment hole. Tightening the locking nut 8 secures it to the side wall of pin II 5, thus fixing the relative position of pin I 4 and pin II 5.

[0041] A handle 10 is provided at the rear end of the screw 6 to facilitate rotation of the screw 6.

[0042] refer to Figure 3 The rear end side wall of pin I4 is rotatably connected to a pin locking piece 7. The pin locking piece 7 has an inclined groove and a fixed length. Pin II5 can be inserted into the inclined groove, which restricts the lateral movement of pin II5 and locks pin II5 onto screw 6. The inner sleeve 2 cannot slide inside the outer sleeve 1, so the height of the mobile platform support legs will not change, and the staff can safely move the mobile platform.

[0043] A mobile platform that adapts to differences in ground flatness, reference Figures 1-7The bottom of the moving platform is equipped with at least three of the aforementioned mobile platform support legs. The operation process is as follows: The telescopic cylinder 3 is activated, extending or retracting to push the inner sleeve 2 to slide within the outer sleeve 1. As the inner sleeve 2 slides, the first adjustment hole 101 on the outer sleeve 1 and the second adjustment hole 201 on the inner sleeve 2 intersect and overlap. When the overlapping area reaches a suitable size and position, the telescopic cylinder 3 stops. Next, the front ends of pins I 4 and II 5 are inserted into the overlapping area, allowing pin II 5 to slide along the screw 6. Then, the handle 10 is rotated to drive the screw 6 to rotate. Through the cooperation of the screw 6 and the locking nut 8, the locking nut 8 is tightened to secure it to the side wall of pin II 5, thus fixing the relative positions of pins I 4 and II 5.

[0044] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
