Detailed Description
In order to clearly explain the technical features of the present patent, the following detailed description of the present patent is provided in conjunction with the accompanying drawings.
As shown in fig. 1-5, the adjusting and moving device comprises a base frame 4 and a traction mechanism connected to the base frame 4, the traction mechanism comprises a traction chain 3 and a traction chain retracting and releasing mechanism 1, and the traction chain 3 is retracted and released through the traction chain retracting and releasing mechanism 1; the number of the traction mechanisms is two, and the two traction mechanisms are symmetrically arranged on two sides of the base frame 4. Therefore, the two traction mechanisms can be synchronously retracted and extended to drive the hydraulic support to translate, so that the hydraulic support is pulled to the base frame from back to front; and the two traction mechanisms can drive the hydraulic support to rotate when being retracted and released, so that the direction of the hydraulic support on the base frame can be adjusted.
The traction mechanism further comprises a pulley mechanism 2, the pulley mechanism 2 comprises a frame 21, a connecting seat 22 and a pulley 23, the frame 21 is connected to the front portion of the traction chain retraction and release mechanism 1, the root of the connecting seat 22 is hinged to the frame 21 through a fixing shaft, the pulley 23 is hinged to the connecting seat 22, and the traction chain 3 is wound around the pulley 23 from back to front and then returns back. Namely, the traction chain is wound around the pulley 23 from one side of the pulley far away from the fixed shaft, so that the pulley and the connecting seat can be freely turned up and down around the fixed shaft.
When in actual use, one end of the traction chain can be connected to the hydraulic support through the hook.
On the one hand, when the traction chain is retracted by the traction chain retracting mechanism, the traction chain is wound around the pulley 23 from the back to the back, so that in the process of pulling the hydraulic support forwards, the traction chain also generates a large acting force on the pulley, the pulley and the connecting seat are forced to be turned upwards to the upper limit position, the traction chain is lifted, a certain distance is reserved between the traction chain and the base frame of the adjusting and moving device, friction between the traction chain and other positions of the adjusting and moving device is avoided when the traction chain pulls the hydraulic support, and the actual use effect and the actual service life of the adjusting and moving device can be effectively guaranteed.
On the other hand, when the traction chain is released by the traction chain retracting mechanism, namely when the traction chain is loosened to be pulled, the traction chain does not produce large acting force on the pulley any more, so that the pulley and the connecting seat swing downwards under the influence of gravity to return to the lower limit position, and the problem of movement interference between the pulley and the hydraulic support is avoided when the direction of the hydraulic support is adjusted.
The frame 21 is frame-shaped, the root of the connecting seat 22 is hinged in the frame 21, the top of the frame 21 is fixedly connected with an upper limiting plate 24, and the bottom of the frame 21 is fixedly connected with a lower limiting plate. Therefore, when the pulley and the connecting seat swing up and down, the up-and-down movement limit position is limited.
Furthermore, the upper limiting plate is positioned above the fixed shaft, and the lower limiting plate is positioned below the pulley. After the connecting seat and the pulley are subjected to external force, the connecting seat and the pulley can be turned upwards to a certain angle until the connecting seat and the pulley abut against the upper limiting plate; when the external force is lost, the device can be turned downwards to be in a horizontal state under the action of gravity.
The root of the connecting seat 22 is also fixedly connected with a limiting rib 25, and when the pulley and the connecting seat swing upwards to the upper limit position, the limiting rib 25 is abutted against the upper limiting plate 24. Can promote the holistic structural strength of connecting seat on the one hand, on the other hand, because pulley and connecting seat upwards swing during to the extreme position, will have great effort between connecting seat and the frame, consequently, support through spacing muscle and last spacing board to lean on and also can show assurance stability in use, avoid the too early quilt of connecting seat to be damaged.
Furthermore, the limiting ribs are triangular prisms. So that the reaction force from the upper limit plate is better and more stably borne when the upper limit plate abuts against the upper limit plate.
The traction chain 3 is a chain or a steel wire rope.
When the connecting seat 22 abuts against the lower limit plate, the pulley 23 is at the lower limit position, and the axis of the pulley 23 is higher than that of the fixed shaft. So that the pulley only turns upwards around the fixed shaft and does not turn downwards after being acted by the traction chain.
The traction chain retraction and release mechanism 1 comprises a linear driving device, one end of the linear driving device is connected with a base frame 4 of the adjusting and moving device, the other end of the linear driving device is connected with a frame 21 in a pulley mechanism, the pulley 23 and the linear driving device are respectively arranged on two sides of a fixed shaft, one end of a traction chain 3 is fixedly connected on the base frame 4 of the adjusting and moving device, and the traction chain 3 winds around one side of the pulley 23 away from the linear driving device from back to front, returns back and is connected with a hydraulic support through a hook; the pulley mechanism 2 is driven to do linear reciprocating motion through a linear driving device.
When the linear drive device is extended, the traction chain is wound around the pulley 23 on the side away from the linear drive device, and therefore the pulley 23 is used as a movable pulley to pull the traction chain; at this moment, the traction chain also will produce the effort on the pulley to force pulley and connecting seat upwards to overturn, thereby "lift up" traction chain, avoid traction chain when dragging hydraulic support, produce the friction with other positions of transferring the device, thereby can effectively guarantee to transfer the actual use effect and the actual life who moves the device.
And when linear drive device contracts, then loosen drawing of pulling chain, at this moment, no external force effect will be on the pulley, and pulley and connecting seat will be under the influence of gravity, and the lower extreme position is got back to in the downward swing to when hydraulic support transfers to, avoid pulley and hydraulic support to appear the problem of motion interference.
The linear driving device is a traction oil cylinder, and the frame 21 is fixedly connected with a piston rod of the traction oil cylinder.
The base frame 4 of the adjusting and moving device is also fixedly connected with a linear slide rail 40 parallel to the linear driving device, the frame 21 is fixedly connected with a slide block matched with the linear slide rail 40, and the slide block is slidably connected in the linear slide rail 40.
