Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction equipment, and in particular relates to a telescopic device for bridge construction. Background Art

[0002] Bridge construction is the process of building a bridge according to the design content; it mainly refers to bridge construction technology and construction organization, construction management, construction quality, etc. During the construction process, there are potholes on the ground, and a telescopic device is needed to adjust the distance between the support bracket of the bridge and the ground.

[0003] Since the simple telescopic mechanism is composed of a simple threaded column and a threaded sleeve, when adjusting the height, dynamic friction occurs between the threaded sleeve and the fulcrum on the ground, and the adjustment resistance is relatively large. A wrench is also required during the adjustment process, which makes it difficult to adjust the height of the telescopic adjustment device in conventional bridge construction.

[0004] For this reason, we propose a telescopic device for bridge construction to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that it is difficult to adjust the height of a telescopic adjustment device in conventional bridge construction, and to propose a telescopic device for bridge construction.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A telescopic device for bridge construction includes a guide column, a threaded barrel is slidably mounted on the upper part of the guide column, a threaded sleeve is mounted on the external thread of the threaded barrel, the lower end of the threaded sleeve is movably supported on the lower part of the guide column, a handle is symmetrically fixedly connected to the side of the threaded barrel, an operating panel is fixedly connected to the upper part of the threaded sleeve, a jacket is fixedly connected to the upper part of the threaded barrel, an elastic hoop is movably mounted on the upper part of the jacket, a bolt is movably inserted through the side of the elastic hoop, and a nut is threadedly mounted on the bolt. Insert the target pillar into the jacket so that the guide column is supported on the ground, then tighten the bolts and nuts with the help of a wrench, use the bolts and nuts to act on the elastic hoop so that the elastic hoop tightens the jacket, and use the jacket to clamp and fix the target pillar, so as to facilitate docking with the target pillar. Hold the handle with one hand to prevent the threaded barrel from rotating, and use the other hand to operate the operating disk to rotate. The operating disk drives the threaded sleeve to rotate, so that the threaded sleeve pushes the threaded barrel upward, and the threaded barrel pushes the jacket upward, which acts on the target pillar upward through the jacket, making it convenient to adjust the support height of the bottom of the target pillar.

[0008] Preferably, a spherical block is fixedly connected to the outside of the handle, and the spherical block is used to block the side of the handle to prevent the handle from hurting the hand.

[0009] Preferably, the guide column comprises a hexagonal column and a support block, and the lower end of the hexagonal column is fixedly connected to the upper end of the support block. After holding the handle, the hand is used to restrict the rotation of the threaded barrel, and the threaded barrel acts on the hexagonal column to prevent the guide column from rotating, thereby improving the stability of the guide column.

[0010] Preferably, the guide column further comprises a support plate, and the support plate is fixedly connected to the lower end of the support block. The support plate is used to increase the support range between the guide column and the ground, thereby reducing the pressure of the guide column on the ground.

[0011] Preferably, the threaded barrel comprises a threaded barrel body, and a hexagonal sliding groove is provided inside the threaded barrel body.

[0012] Preferably, the jacket comprises a jacket body, and a clamping groove is provided on the upper outer wall of the jacket body. The clamping groove is used to clamp the elastic hoop, so as to stabilize the force position of the elastic hoop tightening the jacket body.

[0013] Preferably, the jacket further comprises a tie bar, which is fixedly connected to the upper part of the jacket body. The tie bar is used to block the outer side of the elastic hoop to prevent the elastic hoop from falling off, thereby improving the stability of the connection between the elastic hoop and the jacket.

[0014] Preferably, the elastic hoop comprises an elastic hoop body and a collar, wherein a pair of collars are provided, and the two collars are fixedly connected to the two ends of the elastic hoop body. The bolt is slid through the collar, and then the nut and the bolt are tightened, so that the bolt and the nut tighten the collar, and the elastic hoop body is tightened through the collar, so that the bolt and the nut can control the tightening or loosening of the elastic hoop.

[0015] In summary, the technical effects and advantages of the present invention are as follows:

[0016] 1. Hold the handle with one hand to prevent the threaded barrel from rotating, and use the other hand to operate the operating disk to rotate. The operating disk drives the threaded sleeve to rotate, so that the threaded sleeve pushes the threaded barrel upward, and the threaded barrel pushes the jacket upward. The jacket acts on the target pillar upward, which is convenient for adjusting the support height of the bottom of the target pillar.

[0017] 2. Insert the target pillar into the jacket so that the guide pillar is supported on the ground, and then tighten the bolts and nuts with the help of a wrench. Use the bolts and nuts to act on the elastic hoop so that the elastic hoop tightens the jacket. Use the jacket to clamp and fix the target pillar to facilitate docking with the target pillar.

[0018] 3. After holding the handle, use your hand to restrict the rotation of the threaded barrel, and the threaded barrel acts on the hexagonal column to prevent the guide column from rotating, thereby improving the stability of the guide column.

[0019] 4. Slide the bolt through the collar, and then tighten the nut and bolt so that the bolt and nut tighten the collar, and tighten the elastic hoop body through the collar, making it convenient for the bolt and nut to control the tightening or loosening of the elastic hoop.
