Description

Technical Field

[0001] This utility model relates to the field of foundation formwork technology in foundation construction, specifically a hammering device for foundation formwork steel pipes. Background Technology

[0002] At present, steel pipes are commonly used for foundation formwork reinforcement. The reinforcement work mainly relies on manual hammering of steel pipes. This method is not only inefficient and has high labor costs, requiring a large number of people to work together, making it difficult to meet the needs of large-scale construction, but it is also difficult to ensure the stable depth of the steel pipes in the soil, thus increasing the risk of formwork bulging during concrete pouring. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a hammering device for foundation formwork steel pipes, which enables rapid and stable installation of steel pipes, significantly improving construction efficiency and quality, and reducing labor and material costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hammering device for foundation template steel pipes, comprising a hammer, symmetrically arranged sliding blocks fixedly connected to the hammer, the sliding blocks sliding in a matching guide groove, the guide groove being fixedly connected to the inner wall of a stabilizing cylinder, a clamping assembly for clamping the steel pipe being provided on the stabilizing cylinder, and a lifting assembly for lifting the hammer being provided at the upper end of the guide groove.

[0005] The above structural design enables rapid and stable installation of steel pipes, significantly improving construction efficiency and quality while reducing labor and material costs.

[0006] Preferably, the sliding block is cuboid in shape, and multiple rollers are rotatably connected to the side of the sliding block around the vertical center line.

[0007] The above structural design reduces the resistance encountered by the sliding block during sliding, making it easier for the hammer to fall quickly.

[0008] Preferably, the clamping assembly includes a crossbar threaded through the circumferential wall of the stabilizing cylinder, a clamping rod rotatably connected to the end of the crossbar, and a guide rod fixedly connected to the clamping rod. A hidden groove matching the clamping rod is formed on the wall of the stabilizing cylinder.

[0009] The above structural design makes it easy to clamp the steel pipe, and within a certain range, this device can be applied to steel pipes of different diameters.

[0010] Preferably, a plurality of balls are rotatably connected to the inner sidewall of the clamping rod, and the balls are arranged at equal intervals.

[0011] The above structural design reduces the friction between the steel pipe and the clamping rod, making it easier to drive the steel pipe into the soil.

[0012] Preferably, the lifting assembly includes a rope whose head end is fixedly connected to the hammer, a shaft fixedly connected to the tail end of the rope, a lifting motor connected to the shaft drive, a bearing seat disposed at the end of the shaft, and a pulley disposed above the hammer. The rope passes over the pulley, the pulley is fixedly connected to a support rod, the support rod is fixedly connected to the upper end of the guide groove, the bearing seat and the lifting motor are both fixedly connected to an annular plate, and the annular plate is fixedly connected to a stabilizing cylinder.

[0013] With the above structural design, the hammer is lifted by a lifting motor, which is more convenient and labor-saving.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This device enables rapid and stable installation of steel pipes, significantly improving construction efficiency and quality, greatly saving labor costs, and reducing labor and material costs. Moreover, within a certain range, this device can be applied to steel pipes of different diameters. Attached Figure Description

[0018] Figure 3 This is a top view of the structure of this utility model; Detailed Implementation

[0019] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a hammering device for steel pipes of basic templates, including a hammer 1, a sliding block 2 fixedly connected to the hammer 1, the sliding block 2 sliding in a matching guide groove 3, the guide groove 3 fixedly connected to the inner wall of a stabilizing cylinder 4, the lower end of the guide groove 3 being flush with the lower end of the stabilizing cylinder 4, a clamping assembly for clamping the steel pipe being provided on the stabilizing cylinder 4, and a lifting assembly for lifting the hammer 1 being provided at the upper end of the guide groove 3.

[0020] The upper end of the guide groove 3 is fixedly connected to the annular support plate 31. In order to strengthen the stability of the connection between the support plate 31 and the guide groove 3, a first reinforcing rod 32 is provided between the support plate 31 and the outer side wall of the guide groove 3.

[0021] The sliding block 2 is cuboid in shape, and multiple rollers 21 are rotatably connected to the side of the sliding block 2 around the vertical center line.

[0022] Three sets of clamping assemblies are arranged at equal intervals around the circumferential wall of the stabilizing cylinder 4. Each clamping assembly includes a crossbar 51 threaded through the circumferential wall of the stabilizing cylinder 4, a clamping rod 52 rotatably connected to the end of the crossbar 51, and a guide rod 53 fixedly connected to the clamping rod 52. The guide rod 53 passes laterally through the cylinder wall of the stabilizing cylinder 4. A hidden groove 54 matching the clamping rod 52 is opened on the cylinder wall of the stabilizing cylinder 4. The crossbar 51 is rotatably connected to the clamping rod 52 through a bearing. The center of the clamping rod 52 is fixedly connected to the bearing, and the right end of the crossbar 51 is fixedly connected to the bearing.

[0023] After the operator rotates the horizontal bar 51, the clamping rod 52 moves along with it due to the screw thread. Because of the guide rod 53, the clamping rod 52 cannot rotate around its center. The operator can then move the clamping rod 52 according to the diameter of the steel pipe, allowing it to grip the pipe. When the steel pipe is close to the clamping rod 52, the operator rotates the horizontal bar 51, retracting the clamping rod 52 into the concealed groove 54. This prevents the clamping rod 52 from obstructing the hammer 1 from continuing to strike the steel pipe until it is completely driven into the ground.

[0024] The inner wall of the clamping rod 52 is rotatably connected to multiple balls 55, which are evenly spaced.

[0025] The lifting assembly includes a rope 61 fixedly connected at its head to the hammer 1, a rotating shaft 62 fixedly connected to the tail end of the rope 61, a lifting motor 63 drivenly connected to the rotating shaft 62, a bearing 64 located at the end of the rotating shaft 62, and a pulley 65 located above the hammer 1. The rope 61 passes over the pulley 65, and the pulley 65 is fixedly connected to a support rod 66. The support rod 66 is fixedly connected to the upper end of the guide groove 3. The bearing 64 and the lifting motor 63 are both fixedly connected to an annular plate 67, which is fixedly connected to a stabilizing cylinder 4. A second reinforcing rod 69 is provided between the annular plate 67 and the outer wall of the lower end of the guide groove 3. The support rod 66 is fixedly connected to a support plate 31, and the pulley 65 is correspondingly located above the center of the hammer 1.

[0026] To facilitate the movement of the device by the staff, multiple casters are provided on the lower surface of the annular plate 67, and a handrail is fixedly connected to the annular plate 67 to facilitate the movement of the device by the staff.

[0027] During on-site construction, the steel pipes that need to be driven into the soil are mostly of the same length. Therefore, the length of the guide groove 3 must be greater than the length of the steel pipe required for construction, so that the workers can put the steel pipe into the device through the space between the guide grooves 3. Then the workers push the steel pipe down so that the clamping rod 51 clamps the steel pipe.

[0028] Working principle: First, the operator moves the device to the desired installation location. Then, the operator inserts the steel pipe into the device through the space between the guide grooves 3. The operator then pushes the steel pipe downwards until its lower end contacts the ground. Next, the operator rotates the horizontal bar 51, causing the clamping rod 52 to move closer to the steel pipe until the ball bearing 55 contacts the outer wall of the steel pipe. Then, the operator starts the lifting motor 63, which rotates the shaft 62, which winds up the rope 61, raising the hammer 1 to its highest point. The hammer 1 then falls rapidly under its own weight, striking the steel pipe and driving it into the ground. When the steel pipe is about to approach the clamping rod 52, the operator rotates the horizontal bar 51 in the opposite direction, moving the clamping rod 52 into the hidden groove 54. At this point, the operator starts the lifting motor 63 again to drive the steel pipe completely into the ground.
