[0004] However, when the device is actually used, an operator is required to press down the handle and rotate the pressure plate to facilitate the operation of the device. Utility Model Content

[0005] The main purpose of the utility model is to provide a probe pipe fixing device for coal mine exploration, which can effectively solve the problem that the device is inconvenient to operate when in use.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1As shown, a probe pipe fixing device for coal mine exploration includes a device base 1, two mounting brackets 11 are fixed on the upper end of the device base 1, two sprockets 12 are rotated at the ends of the two mounting brackets 11 that are away from each other, and the two sprockets 12 located on the same side are connected by a chain 13. The sprockets 12 and the chains 13 are both existing technologies, and a plurality of fixing components 2 are fixed between the two chains 13, so that the chains 13 can transmit the fixing components 2 when the sprockets 12 rotate.

[0019] like Figure 2 and Figure 3 As shown, the fixing assembly 2 includes a support rod 21 fixedly connected to the chain plate of the chain 13, so that the chain 13 can transmit the support rod 21 during transmission. Two mounting blocks 22 are fixed on the outer surface of the support rod 21. Two mounting blocks 22 are rotatably mounted on one end close to each other. Two first transmission gears 23 meshing with each other are designed to be meshed with each other, so that the two first transmission gears 23 can rotate in opposite directions. The outer surfaces of the two meshing first transmission gears 23 are fixed with a clamp for clamping the probe. The arc-shaped clamping block 24 is tightly connected. When the two arc-shaped clamping blocks 24 move toward the side close to each other, they can clamp the probe tube. When the two arc-shaped clamping blocks 24 move toward the side away from each other, they can not clamp the probe tube, which is convenient for taking and placing the probe tube. One end of the mounting block 22 is also rotated with a second transmission gear 25 meshing with any first transmission gear 23. Due to the design of the second transmission gear 25, the second transmission gear 25 can make the arc-shaped clamping block 24 move toward the side close to each other or away from each other when it rotates.

[0020] Furthermore, in order to facilitate the two arc-shaped clamping blocks 24 to clamp the probe tube, as shown in FIG. Figure 2 As shown, a clockwork spring 26 is provided between any one of the first transmission gears 23 and the mounting block 22. Except for the front and rear ends, the other two ends of the clockwork spring 26 are respectively fixedly connected to the first transmission gear 23 and the mounting block 22. The clockwork spring 26 is a prior art, so that when the clockwork spring 26 is in a natural state, the two arc-shaped clamping blocks 24 can clamp the probe tube. When the two arc-shaped clamping blocks 24 move to the side away from each other, the clockwork spring 26 can contract, thereby facilitating the resetting of the two arc-shaped clamping blocks 24. At the same time, the elastic force of the clockwork spring 26 can also be used to allow the two arc-shaped clamping blocks 24 to clamp the probe tube.

[0021] In addition, in order to fix the probe tube or facilitate taking out the probe tube when the chain 13 is rotating, Figure 3As shown, a support frame 27 is fixed to one end of the two mounting brackets 11 that are close to each other, and a gear ring 28 with a notch is fixed to the other end of the support frame 27 that is away from the mounting bracket 11. When the sprocket 12 rotates, the chain 13 can transmit the support rod 21. At the same time, when the second transmission gear 25 is meshed with the gear ring 28 and the sprocket 12 continues to transmit the support rod 21, the second transmission gear 25 can rotate. At the same time, due to the design of the second transmission gear 25 and the first transmission gear 23 meshing with each other, the two arc-shaped clamping blocks 24 rotate to the side away from each other, thereby facilitating the taking and placing of the probe tube.

[0022] The specific implementation of this embodiment is as follows: when the device is in use, the sprocket 12 is first rotated to allow the chain 13 to transmit the fixed component 2. When the second transmission gear 25 is engaged with the gear ring 28 and the chain 13 continues to transmit the fixed component 2, the second transmission gear 25 is rotated to allow the two arc-shaped clamping blocks 24 to move to the side away from each other, so that the two arc-shaped clamping blocks 24 do not clamp the probe tube, which facilitates the removal of the probe tube. At the same time, when the second transmission gear 25 is not engaged with the gear ring 28, due to the characteristics of the clockwork spring 26, the two arc-shaped clamping blocks 24 can clamp the probe tube, which facilitates the fixation of the probe tube.

[0023] When the probe tube needs to be stored, the sprocket 12 is rotated in the opposite direction to allow the chain 13 to transmit the support rod 21. When the second transmission gear 25 is engaged with the ring gear 28 and the chain 13 continues to transmit the support rod 21, the two arc-shaped clamping blocks 24 can be moved to the side away from each other, and then the operator places the probe tube between the two arc-shaped clamping blocks 24. When the second transmission gear 25 is not engaged with the ring gear 28, due to the design of the clockwork spring 26, the two arc-shaped clamping blocks 24 move to the side close to each other, thereby clamping and fixing the probe tube.

[0024] It should be noted that the specific installation method, circuit connection method and control method of the sprocket 12, chain 13 and spring 26 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
