Description

Technical Field

[0001] This application belongs to the technical field of auxiliary rod devices, and specifically relates to an auxiliary rod for gas inspection. Background Technique

[0002] With the production of the mine, some roadway design cross-sections are large and the height is high. In some roadways, the pressure is high and the roof is not safe. When personnel enter to inspect gas, there are factors such as inconvenience and insecurity. In addition, when inspecting gas at locations with high roadway height and incomplete support, it is inconvenient to use an optical gas detector for inspection and continuous observation for a long time cannot be carried out. In such locations, a inspection rod is needed to assist in gas inspection.

[0003] Referring to CN215449181U, a mine-use portable gas detector inspection auxiliary rod, which relates to the technical field of detection auxiliary devices, includes a handle, a splint device and a hand-cranked telescopic rod. The splint device clamps the gas detector. The bottom of the hand-cranked telescopic rod is slidably connected to the top of the handle, and the top of the hand-cranked telescopic rod is threadedly connected to the bottom of the splint device. A polymerizable four-corner bracket is provided at the lower end of the handle. The polymerizable four-corner bracket includes four "L"-shaped support columns of the same size. The top of the "L"-shaped support column is hinged to the outer periphery of the handle. At both sides of the bottom of the "L"-shaped support column, there are a matching card slot and a buckle. When the "L"-shaped support columns are closed, they are mutually engaged to form a rectangular column body sleeved on the lower end of the handle. This device is mainly used to facilitate the detection of gas concentration by the detector in the mine. By using this device, the gas detector can be further extended to areas that cannot be reached by hand, thereby effectively broadening the detection range.

[0004] However, there are still the following problems. The auxiliary rod in this device can only fix gas detectors of the same specification, and the width of the gas detector varies according to the specification size, resulting in great limitations in the use of this device and affecting its use. Summary of the Utility Model

[0005] The purpose of this application is to provide an auxiliary rod for gas inspection to solve the problem that the auxiliary rod in the above-mentioned device can only fix gas detectors of the same specification, and the width of the gas detector varies according to the specification size, resulting in great limitations in the use of this device and affecting its use.

[0006] The technical solution adopted by this application is as follows: First, rotate the driving column according to the width of the gas detector. The rotation of the driving column drives the rotation of the double-threaded screw rod. The rotation of the double-threaded screw rod pushes the clamping plate to move through the threaded sleeve until the distance between the clamping plates is the same as the width of the gas detector, then stop rotating the driving column. Next, place the gas detector between the two clamping plates, and then rotate the driving column. The rotation of the driving column drives the rotation of the double-threaded screw rod, and the rotation of the double-threaded screw rod drives the clamping plate to move through the threaded sleeve to clamp and fix the gas detector, so that the device has the effect of fixing gas detectors with different widths.

[0007] In a preferred embodiment, a bearing is embedded on the side surface of the limiting plate. The inner ring surface of the bearing is fixedly connected to the surface of the double-threaded screw rod. The double-threaded screw rod is rotatably connected to the side surface of the limiting plate through the bearing.

[0008] By adopting the above technical solution, by setting the bearing, the double-threaded screw rod can rotate on the side surface of the limiting plate when it is driven.

[0009] In a preferred embodiment, a driving column is fixedly connected to one end of the double-threaded screw rod away from the limiting plate.

[0010] By adopting the above technical solution, by setting the driving column, it is convenient for the user to drive the double-threaded screw rod to rotate.

[0011] In a preferred embodiment, a chute is formed on the upper surface of the support plate. A slider is slidably connected to the inner wall of the chute. One side of the slider away from the inner wall of the chute is fixedly connected to the lower surface of the clamping plate.

[0012] By adopting the above technical solution, by setting the chute and the slider, the clamping plate can stably move on the upper surface of the support plate when it is driven.

[0013] In a preferred embodiment, a handle is fixedly connected to the surface of the rod tube. A connecting rod is fixedly connected to the bottom end of the rod tube. A baffle is fixedly connected to the bottom end of the connecting rod.

[0014] By adopting the above technical solution, by setting the handle, it is convenient for the user to carry the rod tube and convenient for carrying.

[0015] In a preferred embodiment, a threaded hole is formed on the side surface of the telescopic rod. A threaded fixing rod is threadedly connected to the inner wall of the threaded hole. The threaded fixing rod penetrates through the surface of the rod tube, and a driving cylinder is fixedly connected to one end of the threaded fixing rod away from the rod tube.

[0016] By adopting the above technical solution, by setting the driving cylinder, it is convenient for the user to drive the threaded fixing rod to rotate. The rotation of the threaded fixing rod fixes the telescopic rod by using the threaded hole.

[0017] In a preferred embodiment, the number of the clamping plates is two, and the two clamping plates are symmetrically arranged on both sides of the surface of the bidirectional threaded screw rod with the vertical central line on the front surface of the support plate as the axis of symmetry.

[0018] By adopting the above technical solution, by arranging two clamping plates, the external gas detector can be clamped and fixed in cooperation with two rubber clamping pads.

[0019] To sum up, due to the adoption of the above technical solution, the beneficial effects of the present application are as follows:

[0020] 1. In the present application, first, rotate the driving column according to the width of the gas detector. The rotation of the driving column drives the rotation of the bidirectional threaded screw rod. The rotation of the bidirectional threaded screw rod pushes the clamping plate to move through the threaded sleeve. When the distance between the clamping plates is the same as the width of the gas detector, stop rotating the driving column. Then place the gas detector between the two clamping plates. After that, rotate the driving column. The rotation of the driving column drives the rotation of the bidirectional threaded screw rod. The rotation of the bidirectional threaded screw rod drives the clamping plate to move through the threaded sleeve to clamp and fix the gas detector, so that the device has the effect of fixing gas detectors with different widths.
