After the lower pressure plate is pressed downward by the weight, the lower pressure shaft moves downward to drive the telescopic rod to press the clamping rod downward. Since the clamping rod is stuck in the clamping groove, the prying plate is deflected downward away from the side of the running wheel, and the running wheel is deflected upward and pressed on the lower end face of the track, so that the support frame can move, and the walking of the heavy object is relatively stable. When it is necessary to lift the heavy object upward at a certain position, the position of the support frame must be fixed. At this time, the clamping rod can be stuck in the clamping groove away from the side of the stop block. After the lower pressure plate is pressed downward by the weight, the lower pressure shaft moves downward to drive the telescopic rod to press the clamping rod downward. Since the clamping rod is stuck in the clamping groove, the prying plate is deflected downward away from the side of the stop block, and the stop block is deflected upward and pressed on the lower end face of the track, so that the support frame brake is stable in one position, and the heavier the weight, the better the stability effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1-3As shown, the present invention provides a portal hanger for auxiliary construction and transportation of subway railway tracks. Some specific embodiments are described below. Some specific embodiments of a portal hanger for auxiliary construction and transportation of subway railway tracks include two support frames 1. Specifically, the two support frames 1 are placed on two parallel railways respectively. The support frame 1 includes a bottom plate 101, a roller 102 installed under the bottom plate 101, a frame body 103 supported above the bottom plate 101, and a top plate 104 fixed above the frame body 103. The frame body 103 is connected to the bottom plate 101 and the top plate 104 by welding, which is stable and firm. The number of rollers 102 installed under each support frame 1 is at least four, which are divided into two groups and evenly distributed on two tracks of the same railway, that is, there are at least two rollers 102 on each track, which ensures that the support frame 1 moves more smoothly on the rails.

[0028] An elastic component 2 is installed above the top plate 104, and the elastic component 2 specifically includes a through hole 201 that runs through the top plate 104, a lower pressing shaft 202 that is movably installed in the through hole 201 up and down, a lower pressing plate 203 that is welded and fixed above the lower pressing shaft 202, and a compression spring 204 that is supported below the lower pressing plate 203, the through hole 201 is a stepped hole, and the aperture of the upper side is larger than the aperture of the lower side, and the compression spring 204 is installed on the upper side of the through hole 201, so that the lower end of the compression spring 204 is supported at the step of the through hole 201, and when the compression spring 204 is compressed, the lower pressing plate 203 is provided with an upward elastic force. In order to reduce the resistance when the compression spring 204 is lifted upward, the lower pressing shaft 202 can also be set to be hollow. When the lower pressing plate 203 is compressed to close to the top plate 104, the compression spring 204 can be compressed into the through hole 201, and does not affect the downward movement of the lower pressing plate 203.

[0029] A load-bearing rail 3 is installed across the two support frames 1, and the load-bearing rail 3 is connected to the two lower pressure plates 203 by bolts. Equipment and heavy objects can be hung on the load-bearing rail 3 and transported between the two railways along the railway direction.

[0030] The stop device 4 is installed on the bottom plate 101 to switch the support frame 1 between the walking state and the stopping state. The stop device 4 includes a rotating shaft 401 rotatably mounted on the bottom plate 101 and stop members 402 welded and fixed at both ends of the rotating shaft 401. The specific installation method of the rotating shaft 401 is to install it on the bottom plate 101 through two bearing seats so that the rotating shaft 401 can rotate. The two stop members 402 at both ends of the rotating shaft 401 pass through the bottom plate 101 and match with the lower end surfaces of two tracks of the same railway. More specifically, the travel member 402 includes a travel member 4021 and a stop member 4022 that are fixedly connected at an angle. A travel wheel 4023 is installed at the lower end of the travel member 4021, and a stop block 4024 is fixed at the lower end of the stop member 4022. The travel member 402 can swing as the shaft 401 rotates. When one side of the travel wheel 4023 contacts the lower edge of the track, the bottom plate 101 can move on the track. Since there are rollers 102 above the track and travel wheels 4023 below the track, the bottom plate 101 is more stable when moving. An upwardly extending swing arm 403 is welded and fixedly connected above the shaft 401, and a prying plate 404 is welded and fixedly connected to the upper end of the swing arm 403. A plurality of slots 405 are arranged horizontally on the prying plate 404, and the arrangement direction of the slots 405 is perpendicular to the axial direction of the shaft 401, and distributed on both sides of the plane where the shaft 401 and the swing arm 403 are located. In this specific embodiment, four slots 405 are arranged horizontally on the prying plate 404, which are divided into two groups and distributed on both sides of the plane where the rotating shaft 401 and the swing arm 403 are located. The slot 405 can hold the clamping rod 406, and the clamping rod 406 is connected to the lower end of the lower pressing shaft 202 through a telescopic rod 407. More specifically, the telescopic rod 407 includes two upper and lower bolt rods 4071 and a threaded tube 4072 threadedly connected to the two bolt rods 4071. The upper bolt rod 4071 is hinged to the lower pressing shaft 202, and the lower bolt rod 4071 is welded and fixed to the clamping rod 406. When in use, the threaded tube 4072 can be rotated to adjust the length of the telescopic rod 407, and then the angle of the telescopic rod 407 is adjusted so that the clamping rod 406 at the lower end of the telescopic rod 407 is clamped in the slot 405 on one side. A limiting frame 408 is fixed above the clamping slot 405 to prevent the clamping rod 406 from being separated from the prying plate 404 when adjusting the position of the clamping rod 406.

[0031] When it is necessary to move heavy objects along the railway, the clamping rod 406 is stuck in the clamping groove 405 on the side away from the traveling wheel 4023. After the lower pressure plate 203 is pressed downward by the weight, the lower pressure shaft 202 moves downward to drive the telescopic rod 407 to press the clamping rod 406 downward. Since the clamping rod 406 is stuck in the clamping groove 405, the prying plate 404 is tilted downward away from the traveling wheel 4023. Then, the traveling wheel 4023 is tilted upward and pressed against the lower end surface of the track, so that the support frame 1 can move and the movement of transporting heavy objects is relatively stable. When it is necessary to lift the heavy object upward at a certain position, the support frame 1 needs to be fixed in position. At this time, the clamping rod 406 can be clamped in the clamping groove 405 away from the side of the stop block 4024. After the lower pressing plate 203 is pressed downward by the heavy object, the lower pressing shaft 202 moves downward to drive the telescopic rod 407 to press the clamping rod 406 downward. Since the clamping rod 406 is clamped in the clamping groove 405, the prying plate 404 is deflected downward away from the side of the stop block 4024, and the stop block 4024 is deflected upward and pressed on the lower end surface of the track, so that the support frame 1 brakes and stabilizes in one position, and the heavier the weight, the better the stabilization effect. A friction pad 4025 is fixed on the stop block 4024, and the friction pad 4025 contacts the lower end surface of the track to increase the friction force.

[0032] An auxiliary ladder 5 is also installed above the top plate 104. The auxiliary ladder 5 includes a ladder frame 501 hinged on the top plate 104. A lower pressure rod 502 is horizontally installed on the ladder frame 501. Specifically, the two ends of the lower pressure rod 502 are hinged on the two sides of the ladder frame 501. The ladder frame 501 can be deflected to one side. The connection between the lower pressure rod 502 and the ladder frame 501 can be movable. The lower pressure rod 502 remains horizontal during installation and can remain horizontal after the ladder frame 501 is deflected. A horizontal waist-shaped hole 503 is opened on the lower pressure rod 502. Two auxiliary rods 504 extending upward are fixed on the upper end surface of the lower pressure plate 203. The two auxiliary rods 504 are respectively located on both sides of the load-bearing rail 3. The upper ends of the two auxiliary rods 504 are fixedly connected with auxiliary shafts 505. The ends of the auxiliary shafts 505 horizontally penetrate into the waist-shaped hole 503 and can move in the waist-shaped hole 503. When the staff climbs up the ladder frame 501, the ladder frame 501 is deflected due to the weight of the staff, and the pressing rod 502 presses down the auxiliary shaft 505 through the waist hole 503, and then presses down the auxiliary rod 504 and the lower pressing plate 203, so that the lower pressing plate 203 moves down. At this time, the clamping rod 406 is stuck in the clamping groove 405 away from the side of the stop block 4024. Similarly, when the staff climbs up on the ladder frame 501 to perform peripheral construction and maintenance operations, the pressing shaft 202 of the support frame 1 moves downward to drive the telescopic rod 407 to press down the clamping rod 406. Since the clamping rod 406 is stuck in the clamping groove 405, the prying plate 404 is deflected downward away from the side of the stop block 4024, and the stop block 4024 is deflected upward and pressed on the lower end surface of the track, so that the brake of the support frame 1 is stabilized in one position, and the stability of the staff is maintained. As long as the staff is still on the ladder frame 501, the brake will not be released, thereby improving safety.
