Description

Technical Field

[0001] The present invention relates to the technical field of construction, and particularly to a side wall support device for a construction channel. Background Art

[0002] The construction of various channels is very common in water conservancy projects. In order to ensure the stability of the construction channels in water conservancy projects, supporting devices are required to fix and support them during the construction process. Commonly, there are two types: external support and internal support.

[0003] For example, the patent application with the publication number CN113684789A discloses a side wall support device for a construction channel in a water conservancy project. A backing plate is provided at the central position on the upper side of the support member included in the support mechanism. A lead screw is provided inside the lower sides of the first support arm and the second support arm included in the support member. A nut seat is threadedly connected to the outside of the lead screw, and a moving seat is wrapped around the outside of the nut seat. The lower end of the moving seat is rotatably connected to a support plate, and hydraulic cylinders are fixedly connected to the inner corners and the center of the support plate. The output end of the hydraulic cylinder penetrates through the support plate, and a pressing plate is fixedly connected to the output end of the hydraulic cylinder. The side wall of the construction channel in the water conservancy project is supported by setting the support member, and the support member assists the staff to pass through.

[0004] However, the technical solutions disclosed in the above-mentioned existing patents at least have the following disadvantages: The support plate only plays a supporting role for the side wall of the channel, and the passage formed by the combined action of the first support arm and the second support arm can only be used for personnel to pass through. At this time, the support plate cannot further compact the side wall of the channel. Summary of the Invention

[0005] The main object of the present invention is to propose a side wall support device for a construction channel, which can form a passage for personnel to pass through, and at the same time, can further compact the side wall of the channel by using the force exerted on the passage when personnel pass through, aiming to solve the above technical problems.

[0006] To achieve the above object, the present invention proposes a side wall support device for a construction channel, including a base for laying on the bottom wall of the channel, a support plate for abutting against the side wall of the channel, and a backing plate for setting at the mouth of the channel; a support block is provided on the base, and a jacking rod is provided on the support block for jacking the support plate; a transverse guide rod is provided on the support block, and one end of the transverse guide rod facing the side wall of the channel penetrates through the support plate and then inserts into the side wall of the channel; the transverse guide rod is slidably matched with the support plate; a slider is slidably sleeved on the transverse guide rod; a vertical guide rod is provided on the base, and the backing plate is slidably sleeved on the upper part of the vertical guide rod; a driving structure is provided between the backing plate and the slider, and when the backing plate slides down, the driving structure pushes the slider to jack the support plate.

[0007] Preferably, the driving structure is a connecting rod. One end of the connecting rod is rotatably connected to the backing plate, and the other end is rotatably connected to the slider. When the backing plate slides down, it drives the connecting rod to push the slider to tightly press against the support plate.

[0008] Preferably, an elastic reset member is sleeved on the transverse guide rod, and the elastic reset member is located between the slider and the support plate.

[0009] Preferably, the elastic reset member is a spring.

[0010] Preferably, the tightening rod and the support block are in threaded cooperation, and a rotating handle is provided at one end of the tightening rod away from the support plate.

[0011] Preferably, a buffer block is provided at a position of the tightening rod close to the support plate, and the buffer block abuts against the support plate.

[0012] Preferably, a driving handle is provided at one end of the transverse guide rod away from the support plate, and the transverse guide rod and the support block are in threaded cooperation.

[0013] Preferably, a drill bit is provided at the end of the transverse guide rod facing the side wall of the channel.

[0014] Preferably, chutes are provided on both sides of the top surface of the base, and the lower end of the support plate is slidably arranged in the chutes.

[0015] Preferably, the number of the support blocks is two, and the support blocks are installed on the base at intervals; tightening rods are respectively provided on each support block for tightly pressing against the corresponding support plate.

[0016] Due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0017] (1) In the construction channel side wall support device provided by the present invention, by using the backing plate to slidably sleeve on the vertical guide rod and providing a driving structure between the backing plate and the slider, when the construction worker steps on the backing plate, the backing plate moves downward under the downward acting force of the construction worker, so that the driving structure pushes the slider to tightly press against the support plate. Since the support plate can slide along the transverse guide rod towards the side wall of the channel, when the slider tightly presses against the support plate, the support plate plays a role in tamping the side wall of the channel. Therefore, the construction channel side wall support device provided by the present invention can not only form a passage for construction workers, facilitate the passage of construction workers, but also utilize the acting force of the construction workers during passage on the backing plate to further tamp the side wall of the channel, improving the stability effect of the side wall of the channel.

[0018] (2) In the construction channel sidewall support device provided by the present invention, a driving structure is arranged between the connecting rod used as a backing plate and the slider. The two ends of the connecting rod are respectively connected to the backing plate and the slider through rotating shafts. When the backing plate slides down, it drives the connecting rod to push the slider to tightly press against the support plate. The structure is simple, the transmission is reliable, and it is convenient for assembly.

[0019] (3) In the construction channel sidewall support device provided by the present invention, an elastic resetting member is sleeved on the transverse guide rod, and the elastic resetting member is located between the slider and the support plate. Specifically, the elastic resetting member is a spring. When the backing plate moves downward, it will drive the connecting rod to move. At this time, the connecting rod will drive the slider to move along the axis direction of the transverse guide rod. During the movement of the slider, the spring will be compressed, and at this time, the spring will act on the support plate with a force, so that the support plate compacts the sidewall of the channel. When the construction personnel pass over the backing plate and then leave the backing plate, the spring extends and resets, thereby indirectly driving the backing plate to reset. Thus, during the continuous passing of the construction personnel, the support plate will continuously compact the sidewall of the channel.

[0020] (4) In the construction channel sidewall support device provided by the present invention, the jacking rod arranged on the support block is used to tightly press against the support plate, forming a preliminary support for the support plate. During the compaction process, looseness will occur between the jacking rod and the support plate. Therefore, the jacking rod and the support block are set to be in a threaded fit. When looseness occurs, the jacking rod can be rotated to further tightly press against the support plate, forming an effective support for the sidewall of the channel. Description of the Drawings

Detailed Embodiments

[0025] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0027] Combined Figure 1 、 Figure 2 As shown, a side wall support device for a construction channel includes a base 1 for laying on the bottom wall of the channel, a support plate 3 for abutting against the side wall of the channel, and a cushion plate 6 for arranging at the mouth of the channel; a support block 2 is arranged on the base 1, and a jacking rod 5 is arranged on the support block 2 for jacking the support plate 3; a transverse guiding rod 4 is arranged on the support block 2, and one end of the transverse guiding rod 4 facing the side wall of the channel passes through the support plate 3 and then is inserted into the side wall of the channel; the transverse guiding rod 4 is slidably matched with the support plate 3; a slider 8 is slidably sleeved on the transverse guiding rod 4; a vertical guiding rod 7 is arranged on the base 1, and the cushion plate 6 is slidably sleeved on the upper part of the vertical guiding rod 7; a driving structure is arranged between the cushion plate 6 and the slider 8, and when the cushion plate 6 slides down, the driving structure pushes the slider 8 to jack the support plate 3 tightly.

[0028] Through the above structure, the base 1 plays a role in installing and carrying other components, and the support block 2 is used to support and install the transverse guiding rod 4 and the jacking rod 5. By slidably passing the transverse guiding rod 4 through the support plate 3 and inserting one end of the transverse guiding rod 4 into the side wall of the channel, the transverse guiding rod 4 can play a guiding role in the movement of the support plate 3.

[0029] In this embodiment, the transverse guiding rod 4 and the support block 2 are in threaded cooperation. After the transverse guiding rod 4 is threadedly connected to the support block 2, by rotating the transverse guiding rod 4, the transverse guiding rod 4 can be continuously inserted into the side wall of the channel.

[0030] In this embodiment, the jacking rod 5 and the support block 2 are in threaded cooperation. The jacking rod 5 is used to jack the support plate 3 tightly. After the support plate 3 is installed, the jacking rod 5 can be rotated to jack the support plate 3 tightly in the direction perpendicular to the axis, ensuring a continuous force to jack the support plate 3 tightly against the side wall of the channel.

[0031] In this embodiment, the driving structure is a connecting rod 9. One end of the connecting rod 9 is rotatably connected to the backing plate 6, and the other end is rotatably connected to the slider 8. An elastic reset member 10 is sleeved on the transverse guide rod 4, and the elastic reset member 10 is located between the slider 8 and the support plate 3. Specifically, the elastic reset member 10 is a spring.

[0032] The backing plate 6 is actually used to lay on the channel between the two support plates 3. It can form a passage for construction workers to pass through, and the backing plate 6 is slidably sleeved on the upper part of the vertical guide rod 7. During the process of construction workers passing through, they will step on the backing plate 6. At this time, the backing plate 6 will move down along the vertical guide rod 7. During the downward movement of the backing plate 6, it will drive the connecting rod 9 to move. At this time, the connecting rod 9 will drive the slider 8 to move along the axis direction of the transverse guide rod 4. During the movement of the slider 8, it will compress the spring 10. At this time, the spring 10 will act on the support plate 3 with a force, so that the support plate 3 acts on the side wall of the channel for ramming. When the construction workers pass through the passage and leave the backing plate 6, the spring 10 elongates and resets, thereby indirectly driving the backing plate 6 to reset. Thus, during the continuous passing of construction workers, the support plate 3 will continuously ram the side wall of the channel.

[0033] Therefore, the construction channel side wall support device provided in this embodiment can form a passage for construction workers to facilitate personnel passage, and at the same time, it can further ram the side wall of the channel by using the force acting on the backing plate 6 when personnel pass through.

[0034] In this embodiment, a rotating handle 13 is provided at one end of the tightening rod 5 away from the support plate 3, which can be used to conveniently rotate the tightening rod 5. By using the tightening rod 5 provided on the support block 2 to tighten the support plate 3, a preliminary support for the support plate 3 is formed. During the ramming process, looseness will occur between the tightening rod 5 and the support plate 3. When looseness occurs, the tightening rod 5 can be rotated to further tighten the support plate 3 to form an effective support for the side wall of the channel.

[0035] In this embodiment, a buffer block 11 is provided at a position of the tightening rod 5 close to the support plate 3, and the buffer block 11 abuts against the support plate 3. The buffer block 11 can play a buffering role, and at the same time, it can increase the contact area of the tightening rod 5 with the support plate 3, so that the acting force of the tightening rod 5 can act on the support plate 3 more evenly. Specifically, the support plate 3 and the buffer block 11 are connected by bolts, so that the support plate 3 can be disassembled from the buffer block 11 at any time.

[0036] In this embodiment, a driving handle 12 is provided at one end of the transverse guide rod 4 away from the support plate 3. The driving handle 12 facilitates the rotation of the transverse guide rod 4, so that the transverse guide rod 4 can move axially and drill into the side wall of the channel. Further, a drill bit 14 is provided at the end of the transverse guide rod 4 facing the side wall of the channel. By providing the drill bit 14, it is convenient for the transverse guide rod 4 to drill into the side wall of the channel during rotation.

[0037] In this embodiment, sliding grooves 15 are formed on both sides of the top surface of the base 1, and the lower end of the support plate 3 is slidably arranged in the sliding grooves 15. The sliding grooves 15 mainly play a role in positioning and guiding the sliding, so that the support plate 3 can slide along the sliding grooves 15 to the corresponding side wall of the channel during ramming.

[0038] Combined Figure 1 As shown, the number of the support blocks 2 is two, and the support blocks 2 are installed on the base 1 at intervals; a tightening rod 5 is provided on each support block 2 for tightening the corresponding support plate 3.

[0039] The working principle of the present invention is as follows:

[0040] During use, during the installation of the support plate 3, it slides along the sliding groove 15 to the corresponding side wall of the channel, and then the tightening rod 5 is rotated to tighten the support plate 3, and the support plate 3 is tightened against the corresponding side wall of the channel. Then, the transverse guide rod 4 is rotated, and the drill bit 14 is used to drill the transverse guide rod 4 into the corresponding side wall of the channel during rotation. The cushion plate 6 is slidably sleeved on the upper part of the vertical guide rod 7, and it is actually used to be laid on the channel between the two support plates 3, and can form a passage for construction personnel to pass through. During the passage of the construction personnel, the cushion plate 6 will be stepped on, and at this time, the cushion plate 6 will move down along the vertical guide rod 7. During the downward movement of the cushion plate 6, the connecting rod 9 will be driven to move. At this time, the connecting rod 9 will drive the slider 8 to move along the axis direction of the transverse guide rod 4. During the movement of the slider 8, the spring will be compressed, and at this time, the spring will act on a force on the support plate 3 to compact the side wall of the channel by the support plate 3. After the construction personnel pass through the passage, the personnel leave the cushion plate 6, and at this time, the spring 10 extends and resets, thereby indirectly driving the cushion plate 6 to reset. Thus, during the passage of the personnel, the support plate 3 will continuously compact the side wall of the channel.

[0041] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
