Description

Technical Field

[0001] This utility model relates to the construction field, and in particular to an engineering construction equipment, specifically a hydraulic clamp. Background Technology

[0002] In the existing technology, in the construction field, when pouring concrete walls, the tie rod cage is usually fixed first, and then the outer formwork is surrounded around the tie rod cage. The two outer forms of the wall are fixed by tie rods.

[0003] Generally, to facilitate fixing the outer mold, parts of the tie rod extend beyond the mold at both ends. Before subsequent wall processing, these protruding tie rods need to be cut flush with the wall surface. When cutting the tie rods, workers use hydraulic shears to cut from the base of the protruding rod. Because the hydraulic shears require operator intervention, sufficient space needs to be left between the shears and the wall to allow for proper application of force. This results in a residual portion of the tie rod protruding from the wall, requiring workers to use a grinder to grind it flush with the wall surface. This process is cumbersome and wastes manpower and resources. Utility Model Content

[0004] In view of the defects and shortcomings of the existing technology, this utility model provides a hydraulic clamp.

[0005] A hydraulic clamp includes two clamping parts, which are symmetrically arranged and hinged to each other. Both clamping parts are arranged in an arc shape, and a shearing surface is provided on one side of the two clamping parts facing each other.

[0006] Preferably, it includes two operating parts, which are respectively fixedly connected to the two clamping parts, and the two operating parts are brought close to each other to drive the two clamping parts to move closer to each other.

[0007] Preferably, a handle is fixedly connected to the end of the operating part away from the clamp, the handle is arranged perpendicular to the operating part, and the bottom end of the handle is located above the lowest point of the concave surface of the clamp.

[0008] Preferably, it further includes a driving structure for driving the two operating parts to move closer or further apart.

[0009] Preferably, the drive structure includes a hydraulic cylinder, and the two ends of the hydraulic cylinder are detachably connected to the two operating parts respectively.

[0010] Preferably, it further includes a connector, and both of the operating parts are provided with a connector. The connector is rotatably connected to the operating part. The side of the connector away from the operating part has a threaded hole, and the drive structure can be threadedly connected to the connector.

[0011] Preferably, the handle is provided with anti-slip texture.

[0012] Preferably, the handle is provided with a hand grip groove.

[0013] Compared with the prior art, one or more technical solutions of this utility model can achieve at least one of the following beneficial effects:

[0014] (1) The clamps are designed with an arc shape. When handling pull rods that protrude from the wall, the concave part of the clamps contacts the wall, providing sufficient operating space between the hydraulic clamps and the wall, making it easy for workers to operate the hydraulic clamps by hand. After the clamps cut the pull rod that protrudes from the wall, the end face of the top of the pull rod is an arc-shaped concave surface, which is basically flush with the wall or located below the wall. There is no need to grind the pull rod with a grinder, simplifying the operation and saving time and effort.

[0015] (2) The drive structure can be detachably connected to the hydraulic clamp, and manual drive or drive structure drive can be selected according to the needs. Attached Figure Description

[0020] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below with reference to specific examples. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0021] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of protection of this invention.

[0022] Example 1:

[0023] A hydraulic clamp, reference Figure 1 and Figure 2 It includes two clamps 1, two operating parts 2, a drive structure 3, and a support structure. The two clamps 1 are symmetrically arranged and hinged to each other. Both clamps 1 are arranged in an arc shape and each clamp 1 is provided with a shearing surface. The two shearing surfaces are close to each other to shear the object (such as a tie rod).

[0024] Because the clamp part 1 has an arc-shaped structure, when cutting the tie rod extending from the wall, the arc-shaped part of the clamp part 1 directly contacts the wall surface. An operating space is reserved between the hydraulic clamp and the wall surface, facilitating operator work. After cutting off the tie rod extending from the wall, the cutting surface of the tie rod becomes an arc-shaped concave surface, lower than the wall surface, eliminating the need for further grinding of the tie rod. This facilitates subsequent wall processing, simplifies the operation, and saves time and effort.

[0025] Reference Figure 1 Two operating parts 2 are fixedly connected to the ends of the clamps 1 away from the clamps 1. A handle 4 is fixedly connected to the end of the operating part 2 away from the clamps 1. Driving the two handles 4 to move closer to each other will drive the two clamps 1 to move closer to each other. The handles 4 are arranged vertically, perpendicular to the operating parts 2, and the bottom of the handles 4 is higher than the operating parts 2.

[0026] Reference Figure 3 A drive structure 3 is positioned between the two operating parts 2 and is used to drive the two operating parts 2 to move closer or further apart. The drive structure 3 includes a hydraulic cylinder, with both ends of the hydraulic cylinder detachably connected to two handles 4. In this embodiment, the operating parts 2 and the hydraulic cylinder are detachably connected by connecting parts 5. The connecting parts 5 and the operating parts 2 are rotatably connected. There are two connecting parts 5, each rotatably connected to one of the two operating parts 2. A threaded hole is provided on the side of the connecting part 5 away from the operating part 2. Both ends of the hydraulic cylinder are fixedly connected to threaded portions that fit the threaded holes. The hydraulic cylinder is connected to the operating part 2 through the threaded portions. When installing the hydraulic cylinder, first screw the threaded portion of one end of the hydraulic cylinder into the connecting part 5, then align the other end of the hydraulic cylinder with the other connecting part 5, and rotate the connecting part 5 to complete the engagement of the threaded portion and the connecting part 5.

[0027] For the safety of pedestrians and vehicles, the completed roads and walls are inspected, and the protruding parts of the tie rod cages are addressed. If the tie rods to be processed are small in diameter, workers can use hydraulic shears to cut off the protruding parts. The handle 4 should be perpendicular to the operating part 2, with the bottom end of the handle 4 above the shear head 1. Adjusting the operating space above the shear head 1 allows the shear head 1 to directly contact the wall, facilitating worker operation. If the tie rods to be processed are large in diameter or there are many to be processed, workers can install a hydraulic cylinder on the hydraulic shears, using the hydraulic cylinder to perform the cutting action, which is efficient and labor-saving.

[0028] In other embodiments, the threaded portion may also be provided on the operating portion 2, and the connecting member 5 may be rotatably connected to the hydraulic cylinder.

[0029] Example 2:

[0030] The difference from the embodiment is that it also includes a support structure, which includes a support rod and a support base. The lower end of the support rod is fixedly connected to the support base, and the upper end of the support rod is hinged to and detachably connected to the midpoint of the hydraulic cylinder. In practical applications, a universal joint is installed at the midpoint of the hydraulic cylinder, and the upper end of the support rod is threadedly connected to the rotating part of the universal joint. The support rod is a lifting rod, and the height of the hydraulic clamp can be adjusted according to the actual situation.

[0031] When cutting tie rods protruding from the wall, the support structure is installed on the hydraulic shears. The angle and height of the hydraulic shears are adjusted by the universal joint and the support rod so that the jaws of the hydraulic shears contact the wall and cut off the tie rods that protrude from the wall. There is no need for the staff to hold the hydraulic shears by hand.

[0032] The above embodiments are merely preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope of the present utility model based on its technical solution and concept should be covered within the protection scope of the present utility model.
