Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted grouting machine technology, and in particular to a sliding seat lifting mechanism for a vehicle-mounted grouting machine. Background Technology

[0002] In the existing technology, the grouting equipment on the drilling and anchoring grouting trolley is mostly fixed directly at the rear of the vehicle and the loading position is relatively high. On the one hand, this increases the length of the vehicle body, making it inconvenient to pass through narrow tunnels. On the other hand, due to the high loading height, it is necessary to frequently move materials manually or use additional equipment to assist in the operation, which greatly increases the intensity and cost of the operation.

[0003] Therefore, those skilled in the art urgently need to develop a sliding seat lifting mechanism for vehicle-mounted grouting machines. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sliding seat lifting mechanism for a vehicle-mounted grouting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle-mounted grouting machine slide seat lifting mechanism, including a vehicle chassis, the vehicle chassis being connected to a guide rail gantry, a slide seat being slidably disposed at the bottom of the guide rail gantry, a grouting machine base being connected to the bottom of the slide seat, the grouting machine base being connected to the grouting machine, a telescopic hydraulic cylinder being connected to the guide rail gantry, and the output end of the telescopic hydraulic cylinder being connected to the slide seat;

[0006] The inner surfaces of the left and right sides of the guide rail gantry are provided with guide rail gantry grooves. The left and right sides of the slide are respectively located inside the corresponding guide rail gantry grooves, and the left and right sides of the slide are connected to composite wheels.

[0007] The composite wheel includes a welding shaft, which is fixedly connected to a slide block. A bearing pulley is rotatably mounted on the side of the welding shaft away from the slide block, and the bearing pulley contacts the front and rear of the corresponding guide rail gantry groove. The welding shaft has a hollow internal structure, and a top wheel mounting seat is provided on the side of the welding shaft away from the slide block. A top wheel is rotatably mounted on the top wheel mounting seat, and the top wheel is perpendicular to the bearing pulley. The top wheel mounting seat is slidably connected to the welding shaft, and an adjusting bolt is provided on the side of the top wheel mounting seat away from the top wheel. The adjusting bolt is threadedly connected to the welding shaft.

[0008] Preferably, both ends of the telescopic cylinder are rotatably connected to the guide rail gantry and the slide block via pins.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] In this invention, the vehicle-mounted grouting machine slide lifting mechanism uses a telescopic hydraulic cylinder as its power source, connecting the guide rail gantry of the vehicle chassis to the slide, thereby driving the grouting machine to rise and fall. The slide makes sliding contact with the front and rear of the guide rail gantry groove via bearing pulleys, and with the top wheel and side. The composite wheel relies on the bearing pulleys for friction reduction, and the top wheel is adjusted by adjusting bolts to maintain the gap between the slide and the guide rail gantry, ensuring the smooth operation of the slide and improving the stability of the lifting mechanism. Within a limited space, the side-mounted vehicle-mounted grouting machine slide lifting mechanism ensures both the smooth operation of the grouting machine and the ability to adjust the material loading height according to working conditions, thereby reducing the workload.

[0023] Example 1

[0024] Please see Figures 1-5 This utility model provides a technical solution: a vehicle-mounted grouting machine slide seat lifting mechanism, including a vehicle chassis 5, the vehicle chassis 1 is connected to a guide rail gantry 4, a slide seat 7 is slidably arranged at the bottom of the guide rail gantry 4, a grouting machine base 3 is connected to the bottom of the slide seat 7, the grouting machine base 3 is connected to the grouting machine 2, a telescopic cylinder 5 is connected on the guide rail gantry 4, the output end of the telescopic cylinder 5 is connected to the slide seat 7, and both ends of the telescopic cylinder 5 are rotatably connected to the guide rail gantry 4 and the slide seat 7 through pins 8;

[0025] The inner surfaces of the left and right sides of the guide rail gantry 4 are provided with guide rail gantry grooves 41. The left and right sides of the slide 7 are respectively located inside the corresponding guide rail gantry grooves 41, and the left and right sides of the slide 7 are connected with composite wheels 6.

[0026] The side-mounted vehicle-mounted grouting machine slide lifting mechanism uses a telescopic cylinder 5 as a power source. The telescopic cylinder 5 is connected to the guide rail gantry 4 on the vehicle chassis 1 and the slide 7 that slides up and down in the guide rail gantry 4. The telescopic cylinder 5 drives the slide 7 to move up and down in the guide rail gantry 4, thereby driving the grouting machine 2 to move up and down. The composite wheel 6 ensures the smooth operation of the slide 7 in the guide rail gantry 4.

[0027] Example 2

[0028] Please see Figures 5-8 Based on Embodiment 1, the composite wheel 6 includes a welding shaft 63, which is fixedly connected to the slide block 7. A bearing pulley 62 is rotatably provided on the side of the welding shaft 63 away from the slide block 7, and the bearing pulley 62 contacts the front and rear of the corresponding guide rail gantry groove 41.

[0029] Furthermore, the welding shaft 63 has a hollow internal structure. Inside the welding shaft 63, on the side away from the slide block 7, there is a top wheel mounting seat 65. A top wheel 61 is rotatably mounted on the top wheel mounting seat 65. The top wheel 61 and the bearing pulley 62 are arranged perpendicular to each other.

[0030] The slide block 7 slides in contact with the front and rear of the corresponding guide rail gantry groove 41 through the bearing pulley 62, and slides in contact with the side of the corresponding guide rail gantry groove 41 through the top wheel 61. Through multi-directional sliding contact, the stability of the slide block 7 moving up and down is improved.

[0031] Furthermore, the top wheel mounting base 65 is slidably connected to the welding shaft 63, and an adjusting bolt 64 is provided on the side of the top wheel mounting base 65 away from the top wheel 61, and the adjusting bolt 64 is threadedly connected to the welding shaft 63.

[0032] The composite wheel 6 reduces the friction between the slide block and the guide rail gantry 4 through the bearing pulley 62, and adjusts the top wheel 61 through the adjusting bolt 64, so that the slide block 7 can maintain an appropriate gap with the guide rail gantry 4, thereby improving the overall stability of the lifting mechanism.

[0033] The working principle of this utility model is as follows: When in use, the operator drives the slide block 7 to move up and down within the guide rail frame 4 by means of the telescopic cylinder 5, which in turn drives the grouting machine 2 to move up and down. The composite wheel 6 reduces the friction between the slide block and the guide rail frame 4 through the bearing pulley 62. On the other hand, the top wheel 61 is adjusted by means of the adjusting bolt 64 so that the slide block 7 can maintain an appropriate gap with the guide rail frame 4, thereby improving the overall stability of the lifting mechanism.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
