Abstract
Description
Technical Field
[0001] This utility model belongs to the field of safety protection technology, and more specifically, it relates to a heavy hammer buffer tensioning device. Background Technology
[0002] During long-term operation, conveyor belts are prone to tension loss due to factors such as material stretching and fluctuations in operating conditions. At this time, automatic constant tension adjustment is achieved by the gravity of the counterweight tensioning device to ensure the normal operation of the equipment. However, when the conveyor belt suddenly loosens or breaks, the counterweight, which was originally constrained by the traction force of the conveyor belt, will instantly lose its support and fall freely under the action of gravity. It will have a violent rigid collision with the bottom of the mounting frame, causing the counterweight body to be dented and deformed, and the weld seam of the mounting frame to crack and the structure to twist. At the same time, the vibration wave generated by the strong impact will be transmitted to the whole machine, causing the conveyor belt rollers, bearings and other related components to loosen or be damaged, which seriously affects the continuous safe operation of the equipment. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a counterweight buffer tensioning device. This device solves the problem that when the conveyor belt suddenly loosens or breaks, the counterweight, which was originally constrained by the traction force of the conveyor belt, will instantly lose its support and fall rapidly under the action of gravity. It will then violently and rigidly collide with the bottom of the mounting frame, causing the counterweight body to dent and deform, and the weld seams of the mounting frame to crack and the structure to twist. At the same time, the vibration wave generated by the strong impact will be transmitted to the entire machine, causing the conveyor belt rollers, bearings and other related components to loosen or be damaged, seriously affecting the continuous safe operation of the equipment.
[0004] The purpose and effect of this utility model's counterweight buffer tensioning device are achieved through the following specific technical means:
[0005] A counterweight buffer tensioning device includes a positioning mounting base, a positioning connecting base, a guide connecting sleeve, a limiting connecting base, a connecting structure, a limiting structure, a damping elastic element, and a tension steel wire rope. The positioning connecting base is located at the lower part of the positioning mounting base. The guide connecting sleeve is welded to the lower end face of the positioning connecting base. The limiting connecting base is located below the guide connecting sleeve. The connecting structure is disposed at the lower part of the positioning mounting base. The lower end of the damping elastic element is fixedly connected to the inner side of the guide connecting sleeve. The tension steel wire rope passes through the lower part of the limiting connecting base. The limiting structure is disposed on the outer side of the limiting connecting base.
[0006] Furthermore, the connection structure includes a limiting connecting pin and a positioning cotter pin; the lower part of the positioning mounting base and the upper part of the positioning connecting base are provided with a limiting connecting pin, and the lower part of the limiting connecting base is provided with a limiting connecting pin; the end of the limiting connecting pin is provided with a positioning hole, and the positioning cotter pin is provided in the positioning hole.
[0007] Furthermore, the connection structure also includes a wear-resistant collar and anti-loosening washers; a wear-resistant collar is fitted on the outer side of each of the limiting connecting pins; two anti-loosening washers are fitted on the outer side of each of the limiting connecting pins.
[0008] Furthermore, the limiting structure includes an elastic nylon pad; the elastic nylon pad is sleeved on the outside of the lower wear-resistant collar.
[0009] Furthermore, the limiting structure also includes a guide connector; the guide connector is fixedly connected to the upper end face of the limiting connector, the guide connector is slidably connected to the guide connecting sleeve, and the guide connector is fixedly connected to the upper end of the damping elastic element.
[0010] Furthermore, the limiting structure also includes a wire rope clamp seat and a wire rope clamp rod; multiple wire rope clamp seats are provided, multiple wire rope clamp rods are provided, multiple wire rope clamp rods are respectively inserted into the inner side of multiple wire rope clamp seats, and a nut is threaded to the outer side of each wire rope clamp rod. The wire rope clamp seat and the wire rope clamp rod together constitute a rope clamp.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This invention, when the conveyor belt suddenly loosens or breaks, utilizes the synergistic effect of the damping elastic element, guide connecting sleeve, and guide connecting component to quickly absorb the enormous impact force generated by the free fall of the counterweight. This prevents direct rigid contact between the counterweight body and the mounting frame, avoiding damage such as counterweight denting and deformation, mounting frame weld cracking, and structural distortion. It significantly reduces the risk of equipment downtime due to impact. By buffering the impact force, it reduces the transmission of vibration waves to the entire machine, preventing loosening, wear, or damage to conveyor belt rollers, bearings, and other related components due to severe vibration. This ensures the overall safety and reliability of the equipment, thereby reducing the manpower and material costs of equipment maintenance. The wear-resistant collar enhances the wear resistance of the limiting connecting pin, effectively resisting frictional wear during long-term use and extending the service life of key connecting components. The anti-loosening gasket and positioning cotter pin firmly lock the position of the limiting connecting pin, preventing it from slipping during equipment operation. Under the influence of vibration, loosening or detachment may occur, ensuring the stability of the connection structure and avoiding safety hazards caused by connection failure. The elastic nylon pad avoids direct rigid friction between the tension wire rope and the limiting pin, reducing the risk of wire rope wear, fraying, and breakage, while protecting the limiting pin from damage. Simultaneously, its elastic properties buffer local impact loads, preventing the wire rope from sliding on the pin, further improving the stability and durability of the connection. The rope clamp structure, consisting of the wire rope clamp seat and the wire rope clamp rod, can fix the end of the tension wire rope, ensuring a reliable connection between the wire rope and the limiting connector, preventing the weight from slipping and causing loss of control, further enhancing the safety performance of the device. The rope clamp structure is easy to install and disassemble, and simple to operate, effectively improving the convenience of wire rope replacement. The entire device has a simple structure, is easy to install, and can adapt to different working conditions, effectively improving the applicability of the tensioning device.

[0024] The connecting structure includes a limiting connecting pin 101 and a positioning cotter pin 104; a limiting connecting pin 101 is inserted through the lower part of the positioning mounting seat 1 and the upper part of the positioning connecting seat 2, and a limiting connecting pin 101 is inserted through the lower part of the limiting connecting seat 4; a positioning hole is opened at the end of the limiting connecting pin 101, and the positioning cotter pin 104 is inserted in the positioning hole.
[0025] The connecting structure also includes a wear-resistant collar 102 and an anti-loosening washer 103; a wear-resistant collar 102 is fitted on the outer side of each limiting connecting pin 101; and two anti-loosening washers 103 are fitted on the outer side of each limiting connecting pin 101.
[0026] The specific usage and function of this embodiment are as follows: The positioning mounting base 1 is welded to the preset position of the mounting frame on which the weight tensioning device is placed. The positioning mounting base 1 and the positioning connecting base 2 are connected by the limiting connecting pin 101. The wear-resistant collar 102 can improve the wear resistance of the limiting connecting pin 101. The positioning cotter pin 104 inserted into the positioning hole can fix the position of the limiting connecting pin 101. The anti-loosening pads 103 located on both sides of the wear-resistant collar 102 can restrict the position of the wear-resistant collar 102. At the same time, the anti-loosening pads 103 and the positioning cotter pin 104 are pressed together by contact, preventing the positioning cotter pin 104 from falling off due to vibration. When the weight pulls the limiting connecting base 4 by the pulling steel wire rope 6, the damping elastic element 5 can buffer the tension generated by the weight.
[0027] Example 2:
[0028] As attached Figure 2 To be continued Figure 5 As shown:
[0029] Based on Embodiment 1, a limiting structure is also included; the limiting structure is disposed on the outside of the limiting connecting seat 4.
[0030] The limiting structure includes an elastic nylon pad 401; the elastic nylon pad 401 is sleeved on the outside of the wear-resistant collar 102 below.
[0031] The limiting structure also includes a guide connector 402; the guide connector 402 is fixedly connected to the upper end face of the limiting connector 4, the guide connector 402 is slidably connected to the guide connecting sleeve 3, and the guide connector 402 is fixedly connected to the upper end of the damping elastic member 5.
