Description
Technical Field
[0001] This utility model belongs to the technical field of support trolleys, and specifically relates to a multi-functional support trolley. Background Technology
[0002] During the construction and excavation of tunnels or underground roadways, temporary support is often required for the roadways to be excavated to ensure construction safety. Currently, most temporary support methods involve constructing temporary support structures at the locations to be supported. On the one hand, this requires workers to be in the unsupported roadways, posing safety risks, and the efficiency of constructing support structures is low. On the other hand, workers working within the scope of the temporary support structure are limited by space, making it inconvenient to carry out construction at different heights and locations within the roadway, resulting in various inconveniences. Summary of the Invention
[0003] This utility model addresses the problem that current temporary support methods in tunnel excavation often involve constructing temporary support structures at the locations to be supported. This presents several inconveniences, including requiring workers to be in unsupported sections of the tunnel, posing safety risks, and resulting in low efficiency. Furthermore, workers within the temporary support area are limited by space, making it difficult to perform work at different heights and locations within the tunnel. The proposed solution is a multi-functional support trolley. After the trolley assembly moves to the appropriate location, it drives the support components to provide temporary support at that location. Subsequently, it moves the construction platform, carrying workers to perform construction at different locations.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A multi-functional support trolley includes a vehicle body assembly and a support component and a construction platform disposed at the front end of the vehicle body assembly. The support component is used to provide shielding and protection above the construction platform. A rotatable component is rotatably disposed at the front end of the vehicle body assembly. The rotatable component is located in front of a telescopic component. A first support rod is hinged to the rotatable component. A third telescopic component is hinged between the rotatable component and the first support rod. A second support rod is hinged to the upper end of the first support rod. A fourth telescopic component is hinged between the first support rod and the second support rod. The second support rod is hinged to the construction platform. A fifth telescopic component is hinged between the second support rod and the construction platform. The position adjustment of the construction platform's near and far height is achieved by the swinging of the first support rod, the second support rod, and the construction platform. The circumferential movement of the construction platform is driven by the rotation of the rotatable component.
[0005] Preferably, the front end of the vehicle body assembly is hinged with a telescopic component, and a support assembly is hinged above the telescopic component, so that the support assembly can be raised and lowered by extending and retracting the telescopic component.
[0006] Preferably, the telescopic component includes a cylinder and a rod. The rod is slidably disposed inside the cylinder and extends out of the upper end of the cylinder. A first telescopic assembly is fixedly connected to the outer side of the lower end of the cylinder. The output end of the first telescopic assembly is fixedly connected to the upper end of the rod. The first telescopic assembly drives the telescopic component to extend and retract.
[0007] Preferably, a second telescopic component is hinged to the vehicle body assembly. The second telescopic component is located between the telescopic member and the rotating member, and its output end is hinged to the upper end of the cylinder. The telescopic member is driven to swing through the second telescopic component.
[0008] Preferably, the vehicle body assembly is further provided with a rotary drive component for driving the rotary component to rotate.
[0009] Preferably, the upper end of the first support rod is fixedly connected to the first connecting block, one end of the second support rod is fixedly connected to the second connecting block, the free end of the first connecting block and the free end of the second connecting block are hingedly connected, the middle part of the first connecting block is hingedly connected to the first connecting rod, the second connecting block is hingedly connected to the second connecting rod, and the free ends of the first connecting rod and the second connecting rod are both hingedly connected to the end of the fourth telescopic component. The first connecting block and the second connecting block provide storage space for the fourth telescopic component after the second support rod is stored, and at the same time, the first connecting rod and the second connecting rod ensure the swing angle of the second support rod.
[0010] Preferably, a third connecting block is fixedly connected to the end of the second support rod away from the first support rod. A third connecting rod is fixedly connected to the side of the third connecting block away from the second support rod. A sixth connecting rod is fixedly connected to one side of the construction platform. The sixth connecting rod is hinged to the third connecting rod. A fourth connecting rod is hinged to one side of the construction platform. One end of the third connecting block is hinged to the output end of the fourth telescopic component, and the other end is hinged to a fifth connecting rod. The fifth connecting rod is hinged to the fourth connecting rod. The hinged connection position of the fifth connecting rod and the fourth connecting rod is hinged to the output end of the fifth telescopic component. The fourth connecting rod and the fifth connecting rod are located on both sides of the hinged position between the sixth connecting rod and the third connecting rod. The hinged installation of the construction platform is achieved through the hinge of the third connecting rod and the sixth connecting rod. The power output transmission of the fifth telescopic component is achieved through the fourth connecting rod and the fifth connecting rod, while effectively ensuring the swing stroke of the construction platform.
[0011] The beneficial effects of this utility model through the above technical solution are as follows: 1. After the vehicle body assembly moves to the corresponding position, the first support rod, the second support rod, and the construction platform are installed in sequence by hinge. During construction, the worker stands on the construction platform and moves the construction platform in multiple directions and at multiple points in coordination with the rotation of the slewing component to meet the worker's construction needs at various positions.
[0012] 2. This utility model provides support and shielding for the construction platform by setting up liftable and swingable support components, ensuring the safety of workers inside the construction platform, eliminating the need for temporary support structures, and effectively improving work efficiency.
[0013] 3. This utility model uses a telescopic drive mechanism such as a hydraulic cylinder to drive the hinged components to swing. Through the cooperation of multiple connecting blocks and connecting rods, it ensures that when the second support rod swings relative to the first support rod or the construction platform swings relative to the second support rod, the swing amplitude is greater. When stored, the first support rod, the fourth telescopic component, the fifth telescopic component, and the construction platform can be stored in a nearly parallel and close-fitting state, which greatly reduces the space occupied in the stored state and reduces the risk of collision with other equipment when the vehicle assembly moves.

Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 11 As shown, this embodiment provides a multi-functional support trolley, including a vehicle body assembly 1 and a support component 2 and a construction platform 3 disposed at the front end of the vehicle body assembly 1. The support component 2 is used to shield and protect the top of the construction platform 3. The vehicle body assembly 1 adopts tracked wheels to ensure adaptability to different environments. The support component 2 adopts a temporary support device for tunnel excavation disclosed in the authorization announcement number CN221236732U. By storing the second support frame, it avoids collisions with other equipment during the movement of the vehicle body assembly. As an implementation method, support nets are fixedly installed on both the first and second support frames of the support component 2 to prevent stones, soil, etc. from falling and causing injury to workers below.
[0027] As one possible implementation method, the construction platform is a mesh structure for workers to stand on during construction. Guardrails are fixedly installed at intervals along the circumference of the platform to ensure that workers can hold on and limit their movement during construction, preventing them from accidentally stepping into a hole and falling.
[0028] The front end of the vehicle body assembly 1 is rotatably provided with a rotating component 5, which is located in front of the telescopic component 4. The vehicle body assembly 1 is also provided with a rotating drive component 13 for driving the rotating component 5 to rotate. The rotating drive component 13 can be a motor with gear transmission structure, a motor with worm gear structure, or other existing technologies that can drive the rotating component 5 to rotate. The rotating component 5 is a disc-shaped structure.
[0029] A first support rod 6 is hinged to the rotating member 5. A third telescopic component 10 is hinged between the rotating member 5 and the first support rod 6. The third telescopic component 10 is used to drive the first support rod 6 to swing around the rotating member 5. A second support rod 7 is hinged to the upper end of the first support rod 6. A fourth telescopic component 11 is hinged between the first support rod 6 and the second support rod 7. Specifically, a first connecting block 61 is fixedly connected to the upper end of the first support rod 6. One end of the first connecting block 6 is fixedly connected to the upper end of the first support rod 6, and the other end extends obliquely upward toward the front of the vehicle body assembly 1. A second connecting block 62 is fixedly connected to one end of the second support rod 7. One end of the second connecting block 62 is fixedly connected to the end of the second support rod 7. The first connecting block 61 extends at one end towards the free end of the second connecting block 62, and the free end of the first connecting block 61 is hinged to the free end of the second connecting block 62. A first connecting rod 63 is hinged to the middle of the first connecting block 61, and a second connecting rod 64 is hinged to the second connecting block 62. Specifically, the second connecting block 62 is hinged to the second connecting rod 64 at a position away from the first connecting block 61. The free ends of both the first connecting rod 63 and the second connecting rod 64 are hinged to the end of the fourth telescopic component 11. When the fourth telescopic component 11 extends, the second support rod 7 swings around the first connecting block 61 via the second connecting block 62, achieving the effect of the second support rod 7 swinging around the first support rod 6. Figure 1 and Figure 3 As shown, the second support rod 7 is in the swing-open state. When it retracts, the output end of the fourth telescopic component 11 retracts, and the second support rod 7 swings downward (as shown). Figure 8 As shown in the figure, at this time, the first support rod 6, the fourth telescopic component 11 and the second support rod 7 are all nearly parallel.
[0030] The second support rod 7 is hinged to the construction platform 3. A fifth telescopic component 12 is hinged between the second support rod 7 and the construction platform 3. A third connecting block 71 is fixedly connected to the end of the second support rod 7 away from the first support rod 6. The middle part of the third connecting block 71 is fixedly connected to the end of the second support rod 7. A third connecting rod 72 is fixedly connected to the side of the third connecting block 71 away from the second support rod 7. The third connecting rod 72 is inclined away from the fourth telescopic component 11. A sixth connecting rod 75 is fixedly connected to one side of the construction platform 3. The sixth connecting rod 75 is connected to the third connecting rod 72. Rod 72 is hinged; the construction platform 3 is hinged to a fourth connecting rod 73 on one side; one end of the third connecting block 71 is hinged to the output end of the fourth telescopic component 11, and the other end is hinged to a fifth connecting rod 74. The fifth connecting rod 74 is hinged to the fourth connecting rod 73, and the hinged connection position of the fifth connecting rod 74 and the fourth connecting rod 73 is hinged to the output end of the fifth telescopic component 12. The fourth connecting rod 73 and the fifth connecting rod 74 are respectively located on both sides of the hinged position between the sixth connecting rod 75 and the third connecting rod 72. During construction, the output end of the fifth telescopic component 12 is retracted, such as... Figure 1-2As shown, the construction platform rotates around the third link 72, and the fifth link 74 swings around the hinged position at the end of the third connecting block 71, so that the construction platform 3 is in a horizontal state. Furthermore, by rotating the slewing component 5 and adjusting the swing of the first support rod 6 and the second support rod 7, the position of the construction platform 3 can be adjusted, allowing workers on the construction platform 3 to easily perform construction at different positions. And when in the retracted state (i.e., non-construction state), as... Figure 7-8 As shown, the output end of the fifth telescopic component 12 extends out, the construction platform 3 is in a near-vertical state, and the first support rod 6 and the second support rod 7 are both located in the gaps between multiple guardrails on the construction platform 3, reducing the space occupied after storage and avoiding collisions with other equipment during movement.
[0031] The front end of the vehicle body assembly 1 is hinged with a telescopic component 4. The support assembly 2 is hinged to the upper part of the telescopic component 4. The telescopic component 4 includes a cylinder 41 and a rod 42. The rod 42 is slidably disposed inside the cylinder 41 and extends out of the upper end of the cylinder 41. The lower outer side of the cylinder 41 is fixedly connected to a first telescopic component 8. The output end of the first telescopic component 8 is fixedly connected to the upper end of the rod 42. The rod 42 is driven to rise and fall by the first telescopic component 8, and the cylinder 41 limits the rod 42.
[0032] The vehicle body assembly 1 is hinged with a second telescopic component 9. The second telescopic component 9 is located between the telescopic component 4 and the rotating component 5, and its output end is hinged to the upper end of the cylinder 41. The telescopic component 4 is driven to swing through the second telescopic component 9 to ensure the protection of the construction platform 3.
[0033] As one possible implementation method, the rotating part 5 can be disassembled to achieve temporary support function through the support assembly 3 alone.
[0034] It should be noted that the first telescopic component 8, the second telescopic component 9, the third telescopic component 10, the fourth telescopic component 11, and the fifth telescopic component 12 all use hydraulic cylinders.
[0035] When in use, while in motion, such as Figure 2 As shown, the construction platform 3 is in a stowed state, and the two side support frames of the support component 2 are folded to reduce the space occupied by the equipment and avoid collisions with other equipment. At the same time, the support component 2 is placed above the construction platform 3 for shielding and protection. When under construction, such as Figure 1 As shown, the construction platform 3 is first driven to a horizontal position. After the worker stands on it, the rotating component 5 is driven to rotate, and the first support rod 6, the second support rod 7, and the swing of the construction platform 3 are used to make the construction platform 3 reach the construction position while maintaining a near-horizontal state.
