Description

Technical Field

[0001] This application relates to the field of telescopic pole technology, specifically a foldable telescopic pole for supporting engineering equipment. Background Technology

[0002] In the field of engineering construction, according to relevant standards such as GB50500-2013, engineering equipment, as a core component of permanent engineering, encompasses multiple categories including electromechanical equipment, metal structural equipment, and instruments. This equipment needs to be permanently integrated with the building, and its design life must be consistent with the main structure of the project. This places extremely high demands on the stability and safety of the engineering equipment during installation, commissioning, and subsequent maintenance.

[0003] To meet the support needs of engineering equipment in different scenarios, support devices play a crucial role, with telescopic rods used for equipment support being a core component. Existing telescopic rods typically consist of a movable base, a multi-stage hydraulic telescopic rod, and a hydraulic rod. The multi-stage hydraulic telescopic rod is hinged to the movable base, enabling switching between horizontal and vertical positions. The hydraulic rod is also hinged to the base and connected to the middle of the multi-stage hydraulic telescopic rod. Its main function is to drive the multi-stage hydraulic telescopic rod to adjust its angle between 0 and 180 degrees on the base, thereby adapting to the support needs of the engineering equipment in different operating positions.

[0004] However, in actual use, when the multi-stage hydraulic telescopic rod is folded horizontally, a support block is usually placed at the bottom of the head to support its weight. But during the movement of the base, unavoidable bumps are generated, which are directly transmitted to the head of the multi-stage hydraulic telescopic rod, causing it to bounce up and down. In this situation, the head of the multi-stage hydraulic telescopic rod will repeatedly impact the support block, not only generating noise but also accelerating wear on both the support block and the head of the multi-stage hydraulic telescopic rod, affecting the lifespan and performance of the device.

[0005] Therefore, this application provides a foldable telescopic support rod for engineering equipment to solve the above problems. Utility Model Content

[0006] This application provides a foldable engineering equipment support telescopic rod, which aims to solve the problems mentioned in the background art, such as the head of the multi-stage hydraulic telescopic rod reciprocatingly impacting the support block when the existing multi-stage hydraulic telescopic rod for supporting engineering equipment is placed horizontally and the moving base moves, generating noise and aggravating the wear of the support block and the head of the multi-stage hydraulic telescopic rod.

[0007] To achieve the above objectives, this application provides the following technical solution: a foldable engineering equipment support telescopic rod, comprising a movable base, a multi-stage hydraulic telescopic rod hinged to one end of the movable base, and a hydraulic rod hinged to the base for driving the multi-stage hydraulic telescopic rod to adjust the angle from 0 to 180° around the hinge point with the base, wherein the output end of the hydraulic rod is hinged to the middle of the multi-stage hydraulic telescopic rod.

[0008] To reduce head wear of the multi-stage hydraulic telescopic rod, a buffer support mechanism is also included, mounted on the movable base, for supporting the head of the multi-stage hydraulic telescopic rod. The buffer support mechanism includes a base plate fixedly mounted on the base, a support plate positioned directly above the base plate, and a buffer element positioned between the base plate and the support plate. A buffer pad is fixedly connected to the top of the support plate. When the multi-stage hydraulic telescopic rod is folded parallel to the movable base, its head rests on the buffer pad of the buffer support mechanism. When the movable base moves, generating a bumpy force, this force is transmitted to the head of the multi-stage hydraulic telescopic rod. The head exerts pressure on the buffer pad and the support plate. The support plate transmits the force to the buffer element, which absorbs and dissipates the bumpy force through its own deformation or damping action, thereby reducing the vertical swaying amplitude of the head and preventing severe reciprocating impacts between the head and the support structure.

[0009] Preferably, four buffer members are provided, hinged at the four corners between the base plate and the support plate, with adjacent buffer members forming a figure-eight structure. This allows for support and buffering of the support plate from multiple directions, improving the stability and buffering effect of the buffer support mechanism. This structure enables the buffer members to function effectively when subjected to forces from different directions, dispersing pressure and preventing damage to individual buffer members due to excessive force. It also further enhances the buffer protection of the multi-stage hydraulic telescopic rod head, reducing wear and noise.

[0010] Preferably, both the support plate and the buffer pad have a U-shaped structure. Besides limiting the left and right ends of the multi-stage hydraulic telescopic rod, the support plate also better adapts to the shape of the rod's head, increasing the contact area between the head and the support structure, making the support more stable. The U-shaped structure of the buffer pad also more comprehensively covers the bottom and sides of the head, further enhancing the cushioning effect, reducing the head's swaying in the left and right directions, thereby reducing wear and noise, and improving the reliability of the support.

[0011] Preferably, the buffer component includes a hydraulic damper and a buffer spring sleeved on the outside of the hydraulic damper. The bottom of the hydraulic damper is hinged to the base plate, and the output shaft of the hydraulic damper is hinged to the support plate. A fixing plate is fixedly sleeved on the output end of the hydraulic damper, abutting against the top of the buffer spring. The buffer component, composed of a hydraulic damper and a buffer spring sleeved on its outside, combines the elasticity of a spring with the energy dissipation characteristics of a damper, resulting in better buffering effect. The buffer component is constructed by the cooperation of components such as a hydraulic damper and a buffer spring. The buffer spring can quickly absorb impact force and store energy, while the hydraulic damper can dissipate the energy released by the buffer spring, avoiding the generation of rebound force. This allows the bumps of the multi-stage hydraulic telescopic rod head to be quickly and smoothly reduced, effectively reducing the impact between the head and the support structure, and reducing noise and wear.

[0012] Preferably, to facilitate adjustment of the elastic potential energy of the buffer spring: the bottom of the hydraulic damper is threaded with an adjusting plate that abuts against the bottom of the buffer spring. Multiple protruding rods are fixedly connected to the outer wall of the adjusting plate, and these protruding rods are arranged in a ring on the outer wall of the adjusting plate. By changing the position of the adjusting plate, the compression of the buffer spring can be changed, thereby adjusting the elastic potential energy of the buffer spring. This allows the buffer to adapt to the heads of multi-stage hydraulic telescopic rods of different weights or different degrees of bumps, enhancing the applicability and flexibility of the device. The protruding rods also facilitate the operator's rotation of the adjusting plate, making the adjustment process more convenient and effortless.

[0013] Preferably, to facilitate the installation of the multi-stage hydraulic telescopic rod: fixed rods are fixedly connected to both sides of the bottom of the multi-stage hydraulic telescopic rod, and bearing seats are fitted onto the fixed rods. The bearing seats are fixedly mounted on the movable base by bolts. This makes the hinge connection between the multi-stage hydraulic telescopic rod and the movable base more stable and reliable, and facilitates quick and easy installation and disassembly. Simultaneously, the cooperation between the bearing seats and the fixed rods reduces the frictional resistance during the rotation of the multi-stage hydraulic telescopic rod, making angle adjustment smoother, reducing component wear, and extending the service life of the device.

[0014] This application utilizes a buffer support mechanism to effectively reduce wear on the head of a multi-stage hydraulic telescopic rod. The base plate provides a stable mounting foundation for the entire mechanism, the support plate directly bears the weight of the multi-stage hydraulic telescopic rod head, the buffer component cushions the bumps generated during the movement of the base, reducing the impact force between the head and the support structure, and the buffer pad further buffers and protects against direct hard contact between the multi-stage hydraulic telescopic rod head and the support plate. This reduces noise, alleviates wear, extends the service life of the device, and improves its performance.

[0015] The buffer component of this application is composed of a hydraulic damper and a buffer spring. The buffer spring can quickly absorb the impact force and store the force, while the hydraulic damper can consume the energy released by the buffer spring, avoiding the generation of rebound force. This allows the bumps of the multi-stage hydraulic telescopic rod head to be quickly and smoothly reduced, effectively reducing the impact between the head and the supporting structure, and reducing noise and wear.

[0016] This application allows for adjustment of the buffer spring's compression by changing the position of the adjusting plate, thereby regulating the spring's elastic potential energy. This enables the buffer to adapt to different weights of multi-stage hydraulic telescopic rod heads or varying degrees of bumps, enhancing the device's applicability and flexibility. The protruding rod design facilitates operator rotation of the adjusting plate, making the adjustment process more convenient and effortless. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Example 1 This embodiment provides a foldable telescopic support rod for engineering equipment, such as... Figure 1-4As shown, the telescopic rod includes a movable base 1, a multi-stage hydraulic telescopic rod 2 hinged to one end of the movable base 1, and a hydraulic rod 3 hinged to the base 1 for driving the multi-stage hydraulic telescopic rod 2 to adjust its angle from 0-180° around the hinge point with the base 1. The output end of the hydraulic rod 3 is hinged to the middle of the multi-stage hydraulic telescopic rod 2. When support is needed, the output end of the hydraulic rod 3 extends to drive the movable end of the multi-stage hydraulic telescopic rod 2 to rotate upward around its hinge point with the base 1. When the multi-stage hydraulic telescopic rod 2 rotates to the appropriate position, it stops. At this time, the bottom of the hydraulic rod 3, the multi-stage hydraulic telescopic rod 2, and the base 1 form a triangle to ensure the stability of the position of the multi-stage hydraulic telescopic rod 2. Then, the engineering equipment can be supported by adjusting the multi-stage hydraulic telescopic rod 2. When it is necessary to fold the multi-stage hydraulic telescopic rod 2, it is only necessary to retract the output end of the hydraulic rod 3 to drive the movable end of the multi-stage hydraulic telescopic rod 2 to move downward until the multi-stage hydraulic telescopic rod 2 is parallel to the base 1.

[0021] To facilitate the installation of the multi-stage hydraulic telescopic rod 2, fixed rods 21 are fixedly connected to both sides of the bottom of the multi-stage hydraulic telescopic rod 2. Bearing seats 22 are fitted onto the fixed rods 21, and the bearing seats 22 are fixedly mounted on the movable base 1 with bolts. This makes the hinge connection between the multi-stage hydraulic telescopic rod 2 and the movable base 1 more stable and reliable, and facilitates quick and easy installation and disassembly. Simultaneously, the cooperation between the bearing seats 22 and the fixed rods 21 reduces the frictional resistance during the rotation of the multi-stage hydraulic telescopic rod 2, making angle adjustment smoother, reducing component wear, and extending the service life of the device. When installing the multi-stage hydraulic telescopic rod 2, the fixed rods 21 on both sides of its bottom are respectively fitted into the bearing seats 22, and then the bearing seats 22 are fixed to the movable base 1 with bolts, achieving the hinge connection between the multi-stage hydraulic telescopic rod 2 and the movable base 1. When the hydraulic rod 3 drives the multi-stage hydraulic telescopic rod 2 to rotate around the hinge point, the fixed rods 21 rotate within the bearing seats 22. The bearing structure within the bearing seats 22 reduces friction between the two, making the rotation smoother. This structure ensures both the stable installation of the multi-stage hydraulic telescopic rod 2 and the flexibility of its angle adjustment.

[0022] To reduce wear on the head of the multi-stage hydraulic telescopic rod 2, a buffer support mechanism 4 is included, mounted on the movable base 1, to support the head of the multi-stage hydraulic telescopic rod 2. The buffer support mechanism 4 includes a base plate 41 fixedly mounted on the base 1, a support plate 42 positioned directly above the base plate 41, and a buffer element 43 positioned between the base plate 41 and the support plate 42. A buffer pad 44 is fixedly connected to the top of the support plate 42. The buffer support mechanism 4 effectively reduces wear on the head of the multi-stage hydraulic telescopic rod 2. The base plate 41 provides a stable mounting foundation for the entire mechanism; the support plate 42 directly bears the weight of the head of the multi-stage hydraulic telescopic rod 2; the buffer element 43 buffers the bumpy force generated when the movable base 1 moves, reducing the impact force between the head and the support structure; and the buffer pad 44 further buffers and protects the rod, preventing direct hard contact between the head of the multi-stage hydraulic telescopic rod 2 and the support plate 42, thereby reducing noise, mitigating wear, extending the service life of the device, and improving its performance. When the multi-stage hydraulic telescopic rod 2 is folded parallel to the movable base 1, its head rests on the buffer pad 44 of the buffer support mechanism 4. When the movable base 1 moves, generating a bumpy force, this force is transmitted to the head of the multi-stage hydraulic telescopic rod 2. The head exerts pressure on the buffer pad 44 and the support plate 42. The support plate 42 then transmits the force to the buffer component 43. The buffer component 43 absorbs and dissipates the bumpy force through its own deformation or damping action, thereby reducing the vertical swaying amplitude of the head and preventing violent reciprocating impacts between the head and the support structure. The elastic pad 44 is made of rubber or silicone and has anti-slip textures on its surface.

[0023] Four buffer elements 43 are provided, hinged at the four corners between the base plate 41 and the support plate 42, with adjacent buffer elements 43 forming a figure-eight structure. This structure provides support and cushioning to the support plate 42 from multiple directions, improving the stability and cushioning effect of the buffer support mechanism 4. This structure allows the buffer elements 43 to function effectively under forces from different directions, distributing pressure and preventing damage to individual buffer elements 43 due to excessive force. It also further enhances the cushioning protection of the head of the multi-stage hydraulic telescopic rod 2, reducing wear and noise. When the head of the multi-stage hydraulic telescopic rod 2 applies pressure to the support plate 42 or is subjected to bumps, the pressure is transmitted to the four buffer elements 43. Because the adjacent buffer elements 43 are in a figure-eight shape, each buffer element 43 deforms or expands according to the force applied, absorbing energy through its elasticity or damping characteristics. The figure-eight structure allows the buffer elements 43 to cooperate with each other, better coping with forces from different directions and evenly distributing the force across each buffer element 43, thereby improving the overall cushioning performance and structural stability.

[0024] Both the support plate 42 and the buffer pad 44 have a U-shaped structure. Besides limiting the left and right ends of the multi-stage hydraulic telescopic rod 2, the support plate 42 also better adapts to the shape of the head of the multi-stage hydraulic telescopic rod 2, increasing the contact area between the head and the support structure, making the support more stable. The U-shaped structure of the buffer pad 44 also more comprehensively covers the bottom and sides of the head, further enhancing the cushioning effect, reducing the swaying of the head in the left and right directions, thereby reducing wear and noise, and improving the reliability of the support. When the multi-stage hydraulic telescopic rod 2 is folded, its head enters the U-shaped support plate 42 and buffer pad 44. The U-shaped side walls of the support plate 42 restrict the left and right movement of the head of the multi-stage hydraulic telescopic rod 2, preventing the head from swaying due to bumps. At the same time, the U-shaped buffer pad 44 has a larger contact area with the head, which can more evenly distribute the pressure and bump force on the head, and further absorb energy through the elasticity of the buffer pad 44 itself, reducing the vibration of the head, thereby achieving a better protective effect.

[0025] The buffer component 43 includes a hydraulic damper 431 and a buffer spring 432 sleeved on the outside of the hydraulic damper 431. The bottom of the hydraulic damper 431 is hinged to the base plate 41, and the output shaft of the hydraulic damper 431 is hinged to the support plate 42. A fixed plate 433 is fixedly sleeved on the output end of the hydraulic damper 431, which abuts against the top of the buffer spring 432. The buffer component 43 is composed of the hydraulic damper 431 and the buffer spring 432 sleeved on its outside, combining the elasticity of the spring and the energy dissipation characteristics of the damper, resulting in a better buffering effect. The buffer component 43 is formed by the cooperation of components such as the hydraulic damper 431 and the buffer spring 432. The buffer spring 432 can quickly absorb the impact force and store the force, while the hydraulic damper 431 can dissipate the energy released by the buffer spring 432, avoiding the generation of rebound force, so that the bumps of the head of the multi-stage hydraulic telescopic rod 2 can be quickly and smoothly reduced, effectively reducing the impact between the head and the support structure, and reducing noise and wear. When the head of the multi-stage hydraulic telescopic rod 2 is subjected to a bumpy force that presses down on the support plate 42, the support plate 42 transmits the force to the buffer 43. The buffer spring 432 is compressed, absorbing part of the impact force and storing elastic potential energy. At the same time, the output shaft of the hydraulic damper 431 is compressed, and the damping medium inside it generates resistance, consuming some energy. When the bumpy force decreases, the buffer spring 432 releases its elastic potential energy, pushing the support plate 42 upward, while the hydraulic damper 431 hinders this movement, slowly releasing energy to prevent the support plate 42 and the head from rebounding violently, thus achieving effective buffering and shock absorption.

[0026] Example 2 Unlike Embodiment 1, to facilitate adjustment of the elastic potential energy of the buffer spring 432, an adjusting plate 434 is threadedly fitted onto the bottom of the hydraulic damper 431, abutting against the bottom of the buffer spring 432. Multiple protruding rods 435 are fixedly connected to the outer wall of the adjusting plate 434, arranged in a ring on the outer wall. By changing the position of the adjusting plate 434, the compression of the buffer spring 432 can be altered, thereby adjusting its elastic potential energy. This allows the buffer component 43 to adapt to different weights of the multi-stage hydraulic telescopic rod 2 heads or varying degrees of bumps, enhancing the applicability and flexibility of the device. The protruding rods 435 facilitate the operator's rotation of the adjusting plate 434, making the adjustment process more convenient and effortless. By rotating the protruding rods 435, the operator causes the adjusting plate 434 to rotate along the bottom thread of the hydraulic damper 431, thereby changing the height of the adjusting plate 434. When the adjusting plate 434 moves upward, the buffer spring 432 is further compressed, its elastic potential energy increases, and the buffering capacity is enhanced; when the adjusting plate 434 moves downward, the compression of the buffer spring 432 decreases, its elastic potential energy decreases, and the buffering capacity weakens. In this way, the buffering effect of the buffer component 43 can be adjusted according to actual needs to adapt to different working scenarios.

[0027] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0028] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
