The limiting plate 17 is vertically arranged on the sliding plate 14 between the telescopic device 16 and the fixing plate 21, the top of the limiting plate 17 extends to the upper part of the top of the fixing frame 2, a downward notch is formed in the middle of the top of the limiting plate 17, and two guide wheels 24 which are mutually attached are symmetrically and fixedly arranged in the notch from top to bottom; referring to fig. 6, the guide wheel 24 is a groove-shaped guide wheel 24, and a guard ring 25 for preventing the traction cable 18 from being detached is respectively disposed on the wheel body of the upper side of the guide wheel 24 close to the wall-attached support 1 and the lower side of the guide wheel 24 far from the wall-attached support 1.
One end of the traction steel cable 18 is fixedly connected with the top of one end of the expansion device 16 close to the wall-attached support 1, the other end of the traction steel cable is fixedly connected with one side of the top brace 15 close to the wall-attached support 1, a rope body of the traction steel cable 18 penetrates through the two guide wheels 24 in an S shape, and the traction steel cable 18 is in a non-tightening state.
The top brace 15 comprises a top head 26, a top brace screw 27 and a top brace seat 28, two stepped limiting clamping grooves 29 which are used for supporting the guide rail are arranged on the top head 26, the opening size of the limiting clamping grooves 29 is larger than the size of an anti-falling stop lever of the guide rail, two ends of the top brace screw 27 are respectively in threaded connection with the top head 26 and the top brace seat 28, the top brace seat 28 is rotatably connected with the fixing plate 21 through a pin shaft, two tension springs 22 are respectively connected with the front end wall and the rear end wall of the top brace seat 28, and the end part of the traction steel cable 18 is connected with one side, close to the wall-attached support 1, of the top brace seat 28.
Current shore structure, when the guide rail need rise, the fender rod that prevents weighing down of below will stir shore 15 and rotate right, then can not hinder the rise of guide rail, and at shore 15's action of gravity, can make when preventing weighing down the fender rod not contact with shore 15, shore 15 can incline and the front end plate butt of fixed frame 2, consequently can prevent the guide rail sudden drop at the lift in-process, after rising, can make through control guide rail decline a segment distance and fall into spacing draw-in groove 29 in, realize the support to the guide rail.
However, when the guide rail needs to descend, the existing top support 15 needs to rotate the top support screw 27 to adjust the height of the top head 26, so that the top head 26 is separated from the support of the guide rail and the top head 26 gives way to the guide rail, or the guide rail is lifted for a short distance first, and then the top support 15 is pulled to the other side, so that the guide rail is prevented from being blocked when descending; however, because the number of the top braces 15 is large, the top braces 15 need to be manually operated by personnel, and after the top braces are descended, the personnel still need to manually rotate the top brace screw 27 to adjust the height of the top head 26 to support the guide rail anti-falling stop lever or firstly shift the top braces 15 to be inclined towards the guide rail, so that the time and labor are wasted, and the operation risk is increased.
Therefore, in order to solve the above problems, in the present embodiment, the top stay 15 and the telescopic device 16 are fixed together by the sliding plate 14 and can slide left and right relative to the fixed frame 2, then the top stay 15 and the telescopic device 16 are connected by the traction cable 18, the end of the actuating shaft of the telescopic device 16 is fixedly connected with the wall-attached support 1, and the top stay 15 is driven to move left and right by the operation of the telescopic device 16.
As shown in fig. 5, it is a supporting state diagram of the top stay 15 provided by the present invention for the anti-falling bar on the guide rail when the guide rail is stationary, and at this time, the limiting slot 29 faces upward and to the right; when the guide rail rises, the anti-falling stop lever below can stir the top support 15 to rotate rightwards, so that the guide rail cannot be hindered from rising, and under the tension of the second tension spring 22 and the gravity action of the top support 15, when the anti-falling stop lever is not in contact with the top support 15, the top support 15 can be inclined to abut against the front end plate of the fixed frame 2, so that the guide rail can be prevented from falling suddenly in the lifting process.
When the guide rail needs to descend, the actuating shaft of the expansion device 16 contracts, so that the expansion device 16 drives the sliding plate 14 to move towards the wall-attached support 1, at this time, because the traction steel cable 18 is in a non-tightened state and the opening size of the limiting clamping groove 29 is larger than the size of the anti-falling blocking rod of the guide rail, under the action of the tensile force of the tension spring two 22 and the gravity of the top support 15, the top support seat 28 is kept in a butting state with the front end plate of the fixed frame 2, and the limiting clamping groove 29 of the top head 26 deflects and moves downwards at a certain angle relative to the anti-falling blocking rod of the guide rail, in the process of continuous contraction of the actuating shaft of the expansion device 16, the traction steel cable 18 is gradually in a tightened state, and the limiting clamping groove 29 is deflected towards the upper left side, therefore, when the actuating shaft of the subsequent expansion device 16 continuously contracts, the traction steel cable 18 drives the whole top support 15 to move towards the wall-attached support 1 so as to separate from the support of the guide rail, and realize the position of the guide rail, so that the guide rail can normally descend.
After the guide rail is lifted up or lowered, the anti-falling stop lever of the guide rail needs to be supported by the top support 15, at this time, the expansion device 16 is started, in the process that the execution shaft of the expansion device 16 continuously extends, the top support seat 28 is gradually abutted against the front end plate of the fixed frame 2 until the traction steel cable 18 is changed from a tightening state to a non-tightening state, at this time, the top head 26 is moved to the position below the anti-falling stop lever, in the process that the execution shaft of the expansion device 16 continuously extends, the top head 26 gradually rises, so that the limiting clamping groove 29 deviates and rises, the orientation of the limiting clamping groove 29 is gradually changed from the upper left to the upper right, and then the limiting clamping groove 29 can be gradually lifted up from the bottom to support the anti-falling stop lever, and therefore the problems of low efficiency and risk caused by a large number of manual operations are avoided.
In order to facilitate the guiding function of the guide rail, two guiding assemblies are symmetrically arranged at the front end of the fixed frame 2, each guiding assembly comprises a side plate 30 fixedly connected with the front end of the fixed frame 2 and a plurality of guiding rollers 31 which are rotatably arranged on one side, close to each other, of the two side plates 30 in the vertical direction, and the guiding rollers 31 are embedded into grooves on two sides of the guide rail and are relatively rotatably connected with the guide rail.
In order to improve the overall strength, two reinforcing plates 32 are symmetrically arranged between the wall attachment support and the front and rear frame bodies of the fixing frame.
