Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment technology, and more specifically, to an ultra-long stroke sensor mounting device. Background Technology

[0002] A stroke sensor (also known as a displacement sensor or position sensor) is a detection device used to accurately measure the displacement or limit position of moving parts of mechanical equipment. It has wide applications in industrial automation, engineering machinery, turbine monitoring and other fields.

[0003] With the development of coal mining equipment, electro-hydraulic push jacks are now widely used in hydraulic supports for coal mines. In order to improve the performance of these electro-hydraulic push jacks, a stroke sensor is often equipped at the end of the cylinder. The stroke sensor plays a significant role in this process, as the push jack is responsible for moving the support within the hydraulic support.

[0004] Currently, stroke sensors are generally fixed to the bottom of the push jack cylinder by threaded plugs. However, the previous threaded plugs did not have an anti-loosening structure, so the sensors were easy to fall off and required the application of thread-locking adhesive during installation, which made subsequent disassembly very difficult. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an ultra-long stroke sensor mounting device, which aims to solve the problems mentioned in the background art.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An ultra-long stroke sensor mounting device, comprising:

[0008] Cylinder block, wherein a stroke sensor is installed inside the cylinder block; and

[0009] The anti-loosening mechanism is installed on the cylinder body and is used to prevent loosening.

[0010] As a preferred embodiment of this utility model, the anti-loosening mechanism includes a threaded plug, which is threadedly embedded between the inner walls of the cylinder. The outer wall of the threaded plug is provided with equally spaced drill holes, and a plastic block is installed inside each drill hole.

[0011] As a preferred embodiment of this utility model, each of the inner walls of the drill holes is fixedly connected with an elastic metal sheet, and each of the elastic metal sheets is in the shape of a hollow frustum.

[0012] As a preferred embodiment of this utility model, each of the elastic metal sheets has an insertion hole on one side of its outer wall, and each of the plastic blocks has a corresponding plug fixedly connected to one side of its outer wall.

[0013] As a preferred embodiment of this utility model, a hexagonal operating block is fixedly connected to one side of the outer wall of the threaded plug.

[0014] As a preferred embodiment of this utility model, the outer wall of the threaded plug is provided with a wiring hole, and the outer wall of the cylinder is provided with a bayonet.

[0015] Beneficial effects

[0016] Compared with existing technologies, this utility model provides an ultra-long stroke sensor mounting device, which has the following advantages:

[0017] 1. In this solution, the cylinder body is the cylinder body of the push jack in the hydraulic support of coal mine equipment. The stroke sensor is installed on the cylinder body, and the anti-loosening mechanism is set on the cylinder body. The anti-loosening mechanism prevents the threaded plug used to fix the stroke sensor from loosening, which would affect the stability of the stroke sensor and improve its performance.

[0018] 2. In this solution, the threaded plug is used to position the stroke sensor. The plastic block on the drilled hole facilitates the anti-loosening effect during the installation of the threaded plug. When the threaded plug is screwed into the cylinder, the plastic block in the drilled hole is broken during the thread extrusion process, filling the gap between the threads and improving the effectiveness of the anti-loosening mechanism.

[0019] 3. This solution uses a flexible metal sheet to provide convenient support for the plastic block, preventing it from becoming completely embedded in the drilled hole. The combination of insertion holes and slots prevents the plastic block from detaching completely from the flexible metal sheet within the drilled hole, thus protecting the hole and improving the effectiveness of the anti-loosening mechanism.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Example:

[0028] Please see Figure 1-4 An ultra-long stroke sensor mounting device, comprising:

[0029] Cylinder block 1, with stroke sensor 2 installed inside; and

[0030] Anti-loosening mechanism 3 is installed on cylinder 1 and is used to prevent loosening.

[0031] In this embodiment, cylinder 1 is the cylinder of the push jack in the hydraulic support of coal mining equipment. The stroke sensor 2 is installed on cylinder 1, and the stroke sensor 2 can be applied to all electro-hydraulic jacks. Cylinder 1 and stroke sensor 2 are both existing technologies and will not be described in detail here. Anti-loosening mechanism 3 is set on cylinder 1. The anti-loosening mechanism 3 prevents the threaded plug used to fix stroke sensor 2 from loosening, which would affect the stability of stroke sensor 2 and improve its performance.

[0032] Please refer to the specific details. Figure 3-4 As shown, the anti-loosening mechanism 3 includes a threaded plug 301, which is threadedly embedded between the inner walls of the cylinder body 1. The outer wall of the threaded plug 301 is provided with equally spaced drill holes 302, and a plastic block 303 is installed inside each drill hole 302.

[0033] In this embodiment, the threaded plug 301 is used to position the stroke sensor 2. The plastic block 303 on the drill hole 302 provides an anti-loosening effect when the threaded plug 301 is installed. When the threaded plug 301 is screwed into the cylinder 1, the plastic block 303 in the drill hole 302 is destroyed during the thread extrusion process, filling the gap between the threads and improving the performance of the anti-loosening mechanism 3.

[0034] Please refer to the specific details. Figure 3-4 As shown, each drill hole 302 has an elastic metal sheet 304 fixedly connected between its inner walls, and each elastic metal sheet 304 is in the shape of a hollow frustum.

[0035] In this embodiment, the elastic metal sheet 304 provides convenient support for the plastic block 303, avoiding the problem of the plastic block 303 being completely embedded inside the drill hole 302, and improving the effectiveness of the anti-loosening mechanism 3.

[0036] Please refer to the specific details. Figure 3-4 As shown, each elastic metal sheet 304 has an insertion hole 305 on one side of its outer wall, and each plastic block 303 has a corresponding plug 306 fixedly connected to one side of its outer wall.

[0037] In this embodiment, the insertion hole 305 and the plug 306 cooperate, and the plug 306 is made of non-metallic material to prevent the plastic block 303 from completely detaching from the elastic metal piece 304 in the drill hole 302, which would expose the drill hole 302 and further improve the use effect of the anti-loosening mechanism 3.

[0038] Please refer to the specific details. Figure 3 As shown, a hexagonal operating block 4 is fixedly connected to one side of the outer wall of the threaded plug 301.

[0039] In this embodiment, the hexagonal operating block 4 facilitates the screwing of the threaded plug 301, making the installation of the threaded plug 301 convenient.

[0040] Please refer to the specific details. Figure 2-3 As shown, the threaded plug 301 has a wiring hole 5 on its outer wall, and the cylinder body 1 has a bayonet 6 on its outer wall.

[0041] In this embodiment, the wiring hole 5 facilitates the wiring of the stroke sensor 2, the bayonet 6 facilitates the snap-fit ​​of the stroke sensor 2, and the threaded plug 301 facilitates its fixation.

[0042] Working principle: During use, the stroke sensor 2 is inserted into the slot 6 on the cylinder body 1. The cable of the stroke sensor 2 passes through the wiring hole 5 on the threaded plug 301. The threaded plug 301 is installed on the cylinder body 1 by screwing the threaded plug 301 onto the hexagonal operating block 4. During the installation process, the threads on the cylinder body 1 are squeezed by the threaded plug 301, which will break the plastic block 303 inside the drill hole 302. The plastic block 303 fills the gap between the threads to prevent the threaded plug 301 from loosening. The elastic metal sheet 304 provides support for the plastic block 303 to prevent the plastic block 303 from being completely embedded in the drill hole 302. The insertion hole 305 and the slot 306 cooperate to prevent the plastic block 303 from completely detaching from the drill hole 302 and exposing the drill hole 302.

[0043] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
