Description

Technical Field

[0001] The invention relates to the technical field of fire safety, in particular to a self-stabilizing wall-edge walking frame. Background Art

[0002] In the current high-rise building firefighting, high-rise glass cleaning and other operations, corresponding winch counterweight facilities are usually installed on the roof to transfer equipment and personnel to the corresponding height by suspension to carry out firefighting operations on the target or clean the glass.

[0003] During these operations, rope facilities such as safety ropes and functional cables used for suspension need to be pulled down from the roof, and therefore corresponding guide structures such as rollers are required.

[0004] Generally speaking, these guide structures with rollers as the core are set on the winch counterweight bracket, and then extended to a position outside the building through a relatively long cantilever to form a suspended structure outside the building.

[0005] However, in some special building structures, such as those with functional rooms at the top of the building, the installation of the winch counterweight equipment is relatively far from the edge of the building. The cantilever cannot directly extend beyond the building boundary, and the cable inevitably needs to be guided downward along the wall. In this case, the following problems arise: 1. The cable is in direct contact with the building structure and produces friction with the building during the lifting process. Especially at the corners, the friction is huge, which can easily cause cable wear and damage.

[0006] 2. The equipment and personnel working below may need a certain amount of horizontal movement margin, but the cable is in direct contact with the building structure, and due to the interference of friction, it is almost impossible to move. As a result, the lower suspension point has a large angle relative to the top corner point. If the operation is improper, it will swing sharply, posing a safety risk.

[0007] 3. In the scenario where there is no winch counterweight facility installed, how to ensure the safety of the equipment suspended below.

[0008] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0009] The purpose of the present invention is to address the deficiencies of the prior art and thereby provide a self-stabilizing wall-walking frame which can stably walk along a wall, has a high degree of freedom, and ensures the safety of cables.

[0010] In order to achieve the above object, the technical solution adopted by the present invention is: a self-stabilizing wall-edge walking frame, including a corner bracket, an upper wall-edge wheel group, a side wall-edge wheel group and a cable guide wheel group; The corner bracket includes a horizontal portion and a vertical portion, wherein the horizontal portion and the vertical portion form a right angle, and are used to adapt to the corner area of the wall edge; The upper wall wheel assembly is installed on the horizontal part of the corner bracket, and includes a left wall wheel and a right wall wheel. The left wall wheel and the right wall wheel are both deflected toward one side of the wall, so that the upper wall wheel assembly is offset toward one side of the wall during the left and right movement; The side wall is mounted on the vertical portion of the corner bracket along the wheel set, and the rolling direction of the side wall along the wheel set is horizontal; The cable guide wheel assembly is installed on the corner bracket and is used for transmitting the cable.

[0011] Based on the above, the corner bracket includes a horizontal steel plate, a vertical steel plate and a reinforcing rib plate. The vertical steel plate is welded and fixed to the lower center area of the horizontal steel plate, and the reinforcing rib plate is welded and fixed between the horizontal steel plate and the vertical steel plate.

[0012] Based on the above, the upper wall wheel group is installed above the horizontal steel plate through the first wheel group bracket. The first wheel group bracket includes two parallel wing plates. The center position of the wing plate is welded and fixed above the horizontal steel plate. A reinforcing rib plate is welded and fixed at the angle between the wing plate and the horizontal steel plate. The left wall wheel and the right wall wheel are respectively installed at the two ends of the wing plate.

[0013] Based on the above, the left wall wheel and the right wall wheel are both double-wheel structures.

[0014] Based on the above, the side wall wheel group is installed on the inner side of the vertical steel plate through the second wheel group bracket, the second wheel group bracket is a channel steel, and the wheels of the side wall wheel group are installed on the side plate of the channel steel. The number of wheels of the side wall wheel group is at least two pairs.

[0015] Based on the above, the cable guide wheel group includes a horizontal guide wheel group and a vertical guide wheel group; The horizontal guide wheel group is arranged at the front of the horizontal steel plate and above the upper wall wheel group; The vertical guide wheel group is arranged at the rear of the horizontal steel plate and is lower than the horizontal guide wheel group.

[0016] Based on the above, a front sealing plate is welded to the front end of the horizontal steel plate, and a horizontal guide wheel frame is welded to the area where the front sealing plate passes over the upper wall along the wheel group. The horizontal guide wheel group includes a horizontal guide wheel installed in the horizontal guide wheel frame and a first correcting wheel. The first correcting wheel is installed on the rope entry side of the horizontal guide wheel.

[0017] Based on the above, a U-shaped steel is welded to the upper rear end of the horizontal steel plate, and the vertical guide wheel group includes a vertical guide wheel installed in the U-shaped steel and a second correcting wheel, and the second correcting wheel is located on the rope entry side of the vertical guide wheel; The steering angle between the horizontal guide wheel and the vertical guide wheel is 90°.

[0018] Based on the above, the rear end of the horizontal steel plate is bent downward by 90 degrees and a third deviation-correcting wheel is installed.

[0019] Based on the above, the wheels in the upper wall wheel group and the side wall wheel group all adopt a composite structure composed of polyurethane molded bearings and screws, and the wheels in the cable guide wheel group all adopt nylon wheels.

[0020] Compared with the existing technology, the present invention has outstanding substantial features and significant progress. Specifically, the self-stabilizing wall-edge walking frame designed in the present invention can move left and right along the outer edge of the wall, and guide the cable through the cable guide wheel group. On the one hand, it avoids direct contact between the cable and the wall and protects the safety of the cable. On the other hand, it provides space for horizontal movement left and right, which is relatively more flexible and safer.

[0021] In order to avoid the vehicle from falling off the wall edge during left and right movement, the wheels of the upper wall wheel group are deflected toward one side of the wall. During left and right movement, the wheels guide the vehicle toward the side close to the wall, thereby avoiding the danger of the upper wall wheel group falling off the wall edge during movement.

[0022] The provided cable guide wheel set plays a steering and guiding function for the horizontal guidance and vertical rotation angle of the cable, and prevents the cable from deviating through three sets of correcting wheels to ensure the correct guidance of the cable.

[0023] When there is no winch counterweight facility, due to the corner structural characteristics of the self-stabilizing wall edge walking frame, the load of the hanging object below provides a larger friction force, so that the self-stabilizing wall edge walking frame can be stably supported on the wall edge without falling off the wall edge, achieving the purpose of bearing weight, replacing the winch counterweight facility within the load range, and ensuring normal construction.

[0028] The technical solution of the present invention is further described in detail below through specific implementation methods.

[0029] like Figure 1-Figure 4 As shown, a self-stabilizing wall-edge walking frame includes a corner bracket 100, an upper wall-edge wheel group 200, a side wall-edge wheel group 300 and a cable guide wheel group 400.

[0030] The corner bracket 100 includes a horizontal portion and a vertical portion, and a right angle is formed between the horizontal portion and the vertical portion, so as to adapt to the corner area of the wall edge.

[0031] Specifically, in this embodiment, the corner bracket 100 includes a horizontal steel plate 101, a vertical steel plate 102 and a reinforcing rib plate 103. The vertical steel plate 102 is welded and fixed to the lower center area of the horizontal steel plate 101, and the reinforcing rib plate 103 is welded and fixed between the horizontal steel plate 101 and the vertical steel plate 102.

[0032] The upper wall wheel group 200 includes a left wall wheel 202 and a right wall wheel 203. The upper wall wheel group 200 is installed above the horizontal steel plate 101 through a first wheel group bracket 201. The first wheel group bracket 201 includes two parallel wing plates. The center position of the wing plate is welded and fixed above the horizontal steel plate 101. A reinforcing rib plate 103 is welded and fixed at the angle between the wing plate and the horizontal steel plate. The left wall wheel 202 and the right wall wheel 203 are respectively installed at the two ends of the wing plate. The left wall wheel 202 and the right wall wheel 203 are both double-wheel structures.

[0033] To avoid deviation, the left wall wheel 202 and the right wall wheel 203 are both deflected toward one side of the wall. Specifically, with the center position of the first wheel group bracket 201 as the center, the left wall wheel 202 and the right wall wheel 203 are both deflected toward one side of the wall in the extension direction from the center to both ends, so that the upper wall wheel group 200 is offset toward one side of the wall during the left and right movement. The side wall is installed on the vertical portion of the corner bracket 100 along the wheel set 300, and the rolling direction of the side wall along the wheel set 300 is horizontal.

[0034] Specifically, in this embodiment, the side wall wheel group 300 is installed on the inner side of the vertical steel plate 102 through the second wheel group bracket 301, the second wheel group bracket 301 is a channel steel, and the wheels of the side wall wheel group 300 are installed on the side plate of the channel steel. The number of wheels of the side wall wheel group 300 is at least two pairs.

[0035] The cable guide wheel assembly 400 is mounted on the corner bracket 100 and is used to transmit the cable. Specifically, in this embodiment, the cable guide wheel assembly 400 includes a horizontal guide wheel assembly and a vertical guide wheel assembly. In this embodiment, the horizontal guide wheel assembly is arranged at the front of the horizontal steel plate 101 and is located above the upper wall edge wheel assembly 200. In terms of specific structural form, a front sealing plate 404 is welded to the front end of the horizontal steel plate 101, and a horizontal guide wheel frame 403 is welded to the area of the front sealing plate 404 that passes over the upper wall edge wheel assembly. The horizontal guide wheel assembly includes a horizontal guide wheel 401 mounted in the horizontal guide wheel frame 403 and a first correcting wheel 402, which is mounted on the rope entry side of the horizontal guide wheel.

[0036] The vertical guide wheel assembly is located at the rear of the horizontal steel plate 101 and is positioned lower than the horizontal guide wheel assembly. Specifically, a U-shaped steel 405 is welded to the upper rear end of the horizontal steel plate 101. The vertical guide wheel assembly includes a vertical guide wheel 406 mounted within the U-shaped steel 405 and a second correcting wheel 407. The second correcting wheel 407 is located on the rope entry side of the vertical guide wheel 406. The steering angle between the horizontal guide wheel 403 and the vertical guide wheel 406 is 90°. The rear end of the horizontal steel plate 101 is bent downward 90° and is mounted with a third correcting wheel 500.

[0037] In terms of material selection, the wheels in the upper wall wheel group 200 and the side wall wheel group 300 all adopt a composite structure composed of polyurethane molded bearings and screws, which has the advantages of quietness and lubrication. The wheels in the cable guide wheel group 400 all adopt nylon wheels, which has the advantage of wear resistance.

[0038] Working principle description: The self-stabilizing wall edge walking frame is used to be installed in the corner wall edge area of the wall edge 600 and serves as a support frame for the hanging facilities below.

[0039] During the installation process, the upper wall wheel assembly 200 runs on the wall surface, and the side wall wheel assembly 300 runs on the side of the wall, and the two form a 90° angle.

[0040] In the direction of cable travel, the cable first enters from the first correcting wheel 402, passes through the horizontal guide wheel 401, then enters from the second correcting wheel 407, passes through the vertical guide wheel 406, and finally is led out downward from the third correcting wheel 500. The cable applies pressure on the entire self-stabilizing wall edge walking frame from the outside of the wall to the side close to the wall, so that the self-stabilizing wall edge walking frame is only attached to the wall edge position and is not easy to slip off, thereby playing an effective supporting role.

[0041] Even in the absence of winch counterweight facilities, it can provide better supporting capacity.

[0042] When it is necessary to walk left or right and adjust the horizontal position, the self-stabilizing wall-edge walking frame mainly relies on the upper wall-edge wheel group 200 and the side wall-edge wheel group 300 to move together. Among them, the deflection angle design of the upper wall-edge wheel group 200 can make the walking direction always deviate to one side of the wall, avoiding the danger of falling off the wall edge during walking.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for protection of the present invention.
