Description

Technical Field

[0001] The utility model relates to the technical field of teaching supplies, in particular to a physics experiment operating table. Background Art

[0002] With the acceleration of urbanization, especially the continuous expansion of urban scale, road construction has become a very important project. During road paving construction, paving slabs, steel pipes and other equipment need to be placed in designated positions in sequence. Existing construction methods usually use manual placement of slabs, steel pipes or other equipment, or use slings to lift them. When using slings, the equipment needs to be placed on a carrier, and then the carrier is lifted by the sling. The equipment is easy to fall from the carrier, and it is difficult to adjust the placement angle of the equipment. In addition, manual operation requires a large workload and low paving efficiency, which cannot meet the needs of construction. Utility Model Content

[0003] In view of this, in order to solve the problem of low paving efficiency caused by manually placing and adjusting the positions of paving plates in the technical background, this utility model proposes a paving fixture that can be used to clamp paving plates, steel pipes and other equipment, transport them to the designated position, and adjust the angle for placement. The specific technical solution is as follows:

[0004] A paving clamp includes two clamping assemblies, which are symmetrically arranged on a connecting plate below a rotating disk. The clamping assembly includes a connecting arm and a clamping plate at the lower end of the connecting arm. A hydraulic rod is provided above the connecting arm, one end of the hydraulic rod is pin-connected to the bottom of the rotating disk, and the other end of the hydraulic rod is pin-connected to the connecting arm. The clamping assembly is rotated by the extension and retraction of the hydraulic rod, thereby adjusting the distance between the two clamping plates.

[0005] Furthermore, a base is provided above the rotating disk, and a motor is provided on the base. The motor is connected to the rotating disk and drives the rotating disk to rotate.

[0006] Furthermore, a control valve is mounted on the base, and a protective shell is provided on the outside of the control valve to protect the control valve.

[0007] Furthermore, the connecting plates are provided at both ends of the rotating disk, and the upper portion of the clamping assembly can be rotatably connected to the connecting plates.

[0008] Furthermore, the clamping assembly is "L"-shaped, and the inner wall of the clamping plate is a rectangular panel.

[0009] The above technical solution has the following beneficial effects:

[0010] The two clamping assemblies of the utility model are symmetrically arranged below the rotating disk. The clamping assemblies are driven to rotate by the extension and retraction of the hydraulic rod, thereby adjusting the distance between the two clamping plates to clamp the equipment. When the placement angle of the equipment needs to be adjusted, the motor drives the rotating disk to rotate, and the clamping assembly rotates, thereby driving the paving plates or steel pipes and other equipment clamped in the clamping assembly to rotate and adjust their placement angles. The extension and retraction of the hydraulic rod is controlled to open the equipment clamping assembly and put down the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1: See Figure 1 、 Figure 2 and Figure 4 The paving clamp shown includes two clamping assemblies, namely a first clamping assembly 10 and a second clamping assembly 11. The two clamping assemblies are symmetrically arranged on the connecting plate 9 below the rotating disk 2. The clamping assembly includes a connecting arm 1 and a clamping plate 4 at the lower end of the connecting arm 1. A hydraulic rod 5 is provided above the connecting arm 1. One end of the hydraulic rod 5 is pin-connected to the bottom of the rotating disk 2, and the other end of the hydraulic rod 5 is pin-connected to the connecting arm 1. The clamping assembly is rotated by the extension and retraction of the hydraulic rod 5, thereby adjusting the distance between the two clamping plates 4.

[0018] A base 3 is provided above the rotating disk 2, and a motor 6 is provided on the base 3. The motor 6 is connected to the rotating disk 2 and drives the rotating disk 2 to rotate. A control valve 7 is mounted on the base 3, and a protective shell 8 is provided on the outside of the control valve 7 to protect the control valve 7. The connecting plates 9 are provided at both ends of the rotating disk 2, and the top of the clamping assembly can be rotatably connected to the connecting plate 9. The clamping assembly is "L"-shaped, and the inner wall of the clamping plate 4 is a rectangular panel.

[0019] See also Figure 3 As shown, the utility model is installed on the transportation equipment during specific use, the motor 6 is electrically connected to the control valve 7, and after the two clamping assemblies open and clamp the equipment, it is moved to a suitable position by the conveying arm of the transportation equipment, and the equipment is lowered after being rotated to a suitable angle by controlling the rotation of the rotating disk 2.

[0020] The two clamping assemblies of the utility model are symmetrically arranged below the rotating disk 2. The clamping assemblies are rotated by the extension and retraction of the hydraulic rod 5, thereby adjusting the distance between the two clamping plates 4 to clamp the equipment. When the placement angle of the equipment needs to be adjusted, the motor 6 drives the rotating disk 2 to rotate, and the clamping assembly rotates, thereby driving the paving plates or steel pipes and other equipment clamped in the clamping assembly to rotate and adjust their placement angles. The extension and retraction of the hydraulic rod 5 is controlled to open the equipment clamping assembly and put down the equipment.
