Description

Technical Field

[0001] This utility model belongs to the field of track installation technology, specifically a track block tensioner device. Background Technology

[0002] A track is a ring-shaped chain on which a tracked vehicle travels. It is a flexible chain driven by the drive sprocket and surrounds the drive sprocket, road wheels, idler wheels, and track carrier rollers. Tracks consist of track plates and track pins. Track pins connect the track plates to form the track chain. The track plates have holes at both ends for engagement with the drive sprocket and guide teeth in the middle to straighten the track and prevent it from slipping off when the vehicle turns or tilts. The side in contact with the ground has reinforced anti-slip ribs (patterns) to improve the track plate's rigidity and the track's adhesion to the ground. Rubber-coated tracks are currently widely used in various armored vehicles. Rubber-coated tracks have outstanding advantages such as improved shock absorption, reduced noise, improved working environment for armored personnel, reduced fatigue, and excellent road surface protection due to the elasticity of rubber, enabling "all-terrain" combat capability.

[0003] However, the disadvantage of rubber-coated tracks is that the rubber wears out quickly and needs to be replaced frequently. When replacing them, the track needs to be tightened, and then the track pads need to be pulled out and replaced with new track pads. During this process, both ends of the track need to be tightened to facilitate the removal of the track pads. However, traditional track tightening tools are screw-type structures, which require multiple people to work together, are complicated to operate, time-consuming and labor-intensive, and have low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a track block tensioner device to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A track block tensioner device includes a hydraulic cylinder, with crossbars at both ends of the hydraulic cylinder. The two crossbars are respectively connected to the free end of the hydraulic rod and the tail end of the hydraulic cylinder. Slide rods are provided at both ends of the crossbars, and pull rods are slidably mounted on the slide rods.

[0007] Preferably, the free end of the hydraulic rod and the tail end of the hydraulic cylinder are both connected to the center of their corresponding crossbars.

[0008] Preferably, the lower end of the pull rod is provided with a hook, and the corresponding hooks on the two crossbars are symmetrically arranged.

[0009] Preferably, the grooves of the corresponding hooks on the two crossbars are both located on their inner sides.

[0010] Preferably, the upper end of the pull rod is provided with a sliding hole, and the slide rod is slidably inserted into the sliding hole.

[0011] Preferably, the slide bar is also provided with a number of weight-reducing holes for reducing the weight of the slide bar.

[0012] Preferably, guide sleeves are provided on both sides of the front end of the hydraulic cylinder, and two guide rails are provided on the crossbar on the front side of the hydraulic cylinder, with the guide rails slidably inserted into their corresponding guide sleeves.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] In this invention, the two ends of the track are fixed by hooks, and the two ends of the track are pulled by hydraulic cylinders to tighten the track, making it easy to pull out the track plates. The operation is simple, requires no multiple people to cooperate, greatly saves manpower and resources, and is more convenient to use.
