Embodiment 1

[0040] Embodiment 1: a kind of tightening machine based on ratchet and chain structure, as figure 1 and figure 2 As shown, the base 1 and the chain 17 are included, and the chain 17 in this embodiment is a transmission chain.

[0041] Such as Figure 4As shown, the base 1 includes a horizontally arranged bottom plate 101 and two left and right vertical plates 102 vertically fixed on the bottom plate 101. A chain channel for the chain 17 to pass is formed between the two vertical plates 102. The chain channel is a front-to-back communication structure. , the rear portion of the chain passage is the chain inlet of the chain 17, and the front portion of the chain passage is the chain outlet of the chain 17.

[0042] A ratchet mechanism is arranged between the two vertical plates 102, and the ratchet mechanism is located in the chain channel.

[0043] Such as figure 2 and image 3 As shown, one end of the chain 17 is hingedly connected to the riser 102 at the outlet of the ...

Embodiment 2

[0076] Embodiment 2: A tightening machine based on a ratchet wheel and chain structure. The difference between this embodiment and Embodiment 1 is that the untie handle 12 and the cross bar 11 are located between two vertical plates 102 . And the sprocket 3 is located between the unbundling handles 12 . At this time, the vertical plate 102 does not need to be provided with a structure for avoiding the track of the counterclockwise arc movement of the cross bar 11 around the first pin shaft 8 . Other structures are the same as in Embodiment 1.

Embodiment 3

[0077] Embodiment 3: a kind of tightening machine based on ratchet and chain structure, the difference between this embodiment and embodiment 1 is that when the lower end of the triangular plate 9 rotates backward around the second pin shaft 8 to a state greater than 90 degrees ( In the inclined state deflected backward), the second cylinder 10 falls into one of the tooth grooves at the front of the sprocket 3 to block the counterclockwise rotation of the sprocket 3 . In this state, when the chain 17 drives the sprocket 3 to rotate counterclockwise under external pressure, the second cylinder 10 and the sprocket 3 are less likely to disengage, which improves the impact of the non-return ratchet mechanism on the sprocket 3. Stability after locking. Other structures are the same as in Embodiment 1.

Abstract

The invention provides a tightening machine based on ratchet wheel and chain structures, and solves the problem that other construction production is affected due to the fact that a tower crane is needed for assistance when steel pipes are bound on a construction site at present. The machine comprises a base and a chain, the base comprises a horizontally-arranged bottom plate and a left vertical plate and a right vertical plate which are perpendicularly and fixedly arranged on the bottom plate, and a chain channel allowing the chain to penetrate therethrough is formed between the two vertical plates; a ratchet mechanism is arranged between the two vertical plates and located in the chain channel, and a shaft rod of the ratchet mechanism is provided with a tightening handle used for driving the ratchet mechanism to rotate; one end of the chain is hinged to the vertical plate at a chain outlet; the other end of the chain bypasses the lower part of the base and then enters the chain channel through a chain inlet, and the chain penetrates through a gap between a chain wheel and the bottom plate in the chain channel, to mesh with the lower part of the chain wheel and then penetrates out of the chain outlet; and the chain is wound by a circle to form a ferrule for tightening the steel pipe.

Description

technical field [0001] The invention relates to the field of steel pipe binding equipment, in particular to a tightening machine based on a ratchet and chain structure. Background technique [0002] When the steel pipes of the engineering project are leaving the site, the lease contract stipulates that the steel pipes need to be bundled with steel wire rings, and it is difficult to stack the steel pipes into circular stacks, so that it is difficult to cover the steel rings. Now the basic method is to use the tower crane after the steel wire ropes are bundled. Lifting, so that the end face of the steel pipe bundle tends to be circular, put on the steel traveler and then put it down. However, this steel pipe bundling method takes up many hoisting times and a long time of the tower crane, so that it affects other construction and production, and increases the cost of steel pipe bundling. Contents of the invention [0003] In order to solve the problem existing in the backgro...
