Description

Technical Field

[0001] The utility model relates to the technical field of pipe clamp devices, in particular to a multifunctional explosion-proof pipe clamp. Background Art

[0002] Explosion-proof pipe clamps are tools specially designed for use in flammable and explosive environments. They are mainly used to clamp and rotate steel pipes and other cylindrical workpieces. They are especially suitable for the installation and maintenance of oil pipelines and gas pipelines.

[0003] In the prior art, existing explosion-proof pipe clamp devices generally do not have a lubrication structure. During actual use, the internal movable structures are greatly worn, resulting in larger gaps between the movable structures, affecting the normal use of the explosion-proof clamp device and being detrimental to the service life of the explosion-proof pipe clamp device. In addition, most existing explosion-proof pipe clamp devices require manual screwing of the threaded block to push the second clamp block to move left and right. The actual operation takes a long time, which affects the working efficiency of the explosion-proof pipe clamp device during actual use. For this reason, a multifunctional explosion-proof pipe clamp is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a multifunctional explosion-proof pipe clamp to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a multifunctional explosion-proof pipe clamp, comprising: a fixed clamp block, a limiting sleeve installed on the fixed clamp block, a sliding clamp block is provided on one side of the limiting sleeve, and a threaded sleeve is installed on the bottom of the sliding clamp block.

[0006] A threaded rod is provided in the inner sleeve of the threaded sleeve, a driving box is installed at the bottom of the threaded rod, a fixed sleeve on the top of the driving box is provided with an oil dripping pipe, and a controller is provided on the lower side of the oil dripping pipe.

[0007] Preferably, one side of the limiting sleeve is fixedly connected to the fixed clamping block, and the other side of the limiting sleeve is slidably connected to the sliding clamping block.

[0008] Preferably, auxiliary frames are fixedly connected to both sides of the bottom of the fixed clamping block, and the driving box and the fixed clamping block are fixedly connected via a short rod.

[0009] Preferably, two oil dripping tubes are provided and symmetrically arranged on the top of the driving box, a sealing cap is threadedly connected to the top of the oil dripping tube, and one side of the controller is fixedly connected to the driving box.

[0010] Preferably, a cavity is provided at the bottom of the sliding clamp block, the threaded sleeve is fixedly installed in the cavity, and a limiting ring is provided on the fixed sleeve at the bottom of the sliding clamp block.

[0011] Preferably, a transmission gear is fixedly sleeved at the bottom of the threaded rod, a linkage gear is meshed on one side of the transmission gear, a driven gear is provided on one side of the linkage gear, and both the linkage gear and the driven gear are fixedly sleeved on the upper shaft.

[0012] Preferably, a lower shaft is provided on the lower side of the upper shaft, a driving gear is fixedly sleeved on one end of the lower shaft, and the other end of the lower shaft is fixedly connected to the output end of the small motor. The small motor and the drive box are fixedly connected through a long rod, and the small motor and the controller are electrically connected. The upper shaft and the lower shaft are both rotatably sleeved in the drive box.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The auxiliary frames fixedly installed on both sides of the fixed clamp are convenient for pressing and exerting force when using the explosion-proof pipe clamp. The drive box is used to protect and support the transmission mechanism inside it. The drive box is fixedly installed on one side of the fixed clamp through a short rod. By fixing the drip tube on the top of the drive box, it is avoided to disassemble the drive box for lubrication inside. The lubricating liquid is dripped into the drip tube so that the lubricating oil drips on the teeth of each gear. During the meshing transmission process of each gear, the lubricating oil can be evenly applied to the gear teeth, thereby realizing the oiling function inside the drive box, thereby reducing the wear of the meshing between the gears, ensuring the normal use of the explosion-proof pliers, and extending the service life of the explosion-proof pliers.

[0015] 2. When the sliding clamp needs to be moved, the small motor is started by operating the controller, and through a series of gear transmissions, the threaded rod is driven to rotate, and then the sliding clamp is driven to slide in the limit sleeve through the threaded sleeve provided on the threaded rod, thereby adjusting the position of the sliding clamp. The bottom fixed sleeve of the sliding clamp is provided with a limit ring, which limits the sliding clamp to prevent it from sliding out of the limit sleeve. When the sliding clamp is adjusted to a suitable position, the small motor is stopped by the controller, and the traditional twisting method is replaced by the electric control drive method, which makes it convenient for the operator to adjust the position of the sliding clamp and reduces the time required for the movement of the sliding clamp, which is beneficial to the working efficiency when the explosion-proof pliers are actually used and also improves the convenience of using the explosion-proof pliers.

During the meshing transmission process of each gear, the lubricating oil can be evenly applied to the gear teeth, thereby realizing the oiling function inside the driving box 6, thereby reducing the wear of the meshing between the gears, ensuring the normal use of the explosion-proof pliers, and extending the service life of the explosion-proof pliers.
