[0001] The utility model belongs to the technical field of building construction safety protection, and particularly relates to a foldable height limiting device for climbing work equipment. Background Art

[0002] Aerial climbing vehicle is a type of climbing equipment that allows people to stand on the vehicle platform to perform aerial work and other activities. At present, during the use of engineering construction climbing equipment, brake limit devices are installed to reduce the risk of safety accidents when the machinery is climbing. For example, the patent with publication number CN219751855U discloses an anti-extrusion limit device for aerial work vehicles. By installing limiters that are higher than the work platform at the four corners of the aerial work vehicle, when the limiters come into contact with structures such as the roof of the building, the aerial work vehicle will be restricted from continuing to rise to ensure construction safety. However, the problem with this type of height limit device is that the limiter is always higher than the aerial work equipment, which makes it easy for the aerial work equipment to be damaged by collision when it moves in a non-working state, resulting in a higher risk of safety accidents during the subsequent use of the climbing equipment, and there are major safety hazards. Utility Model Content

[0003] In response to the above-mentioned problems in the prior art, the present application proposes a foldable height limit device for climbing work equipment, which uses a foldable bracket to install the limiter on the climbing work equipment.

[0005] The foldable bracket includes a vertical pole and a support pole; the limiter is installed on the top of the vertical pole, and the bottom of the vertical pole is hinged to the climbing work equipment; the top of the support pole is hinged to the vertical pole, and the bottom of the support pole is hinged to the climbing work equipment to support the vertical pole in an upright state;

[0006] The contact switch is installed on the side wall of the climbing work equipment, and when it contacts the upright pole, the contact switch, the limiter and the circuit of the climbing work equipment are connected to form a loop.

[0007] Furthermore, the bottom of the vertical pole and the bottom of the support pole are in the same horizontal plane.

[0008] Furthermore, the support rod includes a first support member, a second support member and a locking member; one end of the second support member is hinged to the vertical pole, and the other end has a channel toward the vertical pole; one end of the first support member extends into the channel, and the other end is hinged to the climbing work equipment; the locking member connects the first support member and the second support member.

[0014] The beneficial effects of the utility model include:

[0015] Using a foldable bracket to install the limiter on the climbing equipment can solve the problems of height limit braking of the climbing equipment and the inability to pass through obstacles normally due to the height of the limiter when not in operation.

[0023] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-Figure 5 As shown, the height limit device of the foldable climbing work equipment of the present invention includes a limiter 6, a contact switch 3 and a foldable bracket;

[0025] The foldable bracket includes a vertical pole 5 and a support pole; a limiter 6 is installed at the top of the vertical pole 5, and the bottom of the vertical pole 5 is hinged to the climbing work equipment 10; the top of the support pole is hinged to the middle of the vertical pole 5, and the bottom of the support pole is hinged to the climbing work equipment 10 to support the vertical pole 5 in an upright state;

[0026] The contact switch 3 is installed on the side wall of the climbing work equipment 10, and when it contacts the upright pole 5, the circuit connection of the contact switch 3, the limiter 6 and the climbing work equipment 10 forms a loop.

[0027] The bottom of the vertical rod 5 and the bottom of the support rod are in the same horizontal plane. Whether the vertical rod 5 is in an upright state is determined by whether the bottoms of the vertical rod 5 and the support rod are in the same horizontal line. The angle between the vertical rod 5 and the support rod is 45 degrees.

[0028] The support rod includes a first support member 1, a second support member 8 and a locking member; one end of the second support member 8 is hinged to the vertical pole 5, and the other end has a channel facing the vertical pole 5; one end of the first support member 1 extends into the channel, and the other end is hinged to the climbing work equipment 10; the locking member connects the first support member 1 and the second support member 8.

[0029] The locking member includes a spring rivet 7 secured to the second support member 8. A positioning hole is provided in the first support member 1 for the spring rivet 7 to extend into. The passageway comprises a slot in the second support member 8, into which one end of the first support member 1 extends. Once the spring rivet 7 is inserted into the positioning hole, the first and second support members 1 and 8 are fixed relative to each other. Once the spring rivet 7 is released from the positioning hole, the first support member 1 can be flipped relative to the second support member 8 or inserted into the slot of the second support member 8, shortening or collapsing the support rod.

[0030] The first support member 1 is hinged to the second support member 8, and the two can rotate relative to each other. When the first support member 1 and the second support member 8 are folded relative to each other, the first support member 1 is embedded in the groove of the second support member 8, and the spring rivet 7 is aligned with the positioning hole and automatically extends into the positioning hole under the action of the spring, locking and fixing the first support member 1 and the second support member 8.

[0031] In some embodiments, the first support member 1 and the second support member 8 can also be relatively slidably matched. For example, the first support member 1 is inserted into the groove of the second support member 8, and then the first support member 1 and the second support member 8 are locked and fixed after aligning the positioning hole with the spring rivet 7.

[0032] An angle bracket 4 is provided at the bottom of the vertical pole 5 and is made of steel. The angle bracket 4 is hinged to the climbing operation equipment 10 .

[0033] In this embodiment, all the above-mentioned articulations are realized by articulation bolts 2. The height of the limiter 6 is determined according to the height limit value, thereby determining the length of the vertical pole 5 and the height at which the angle bracket 4 at the bottom of the vertical pole 5 is articulated with the climbing equipment 10, and further determining the height of the bottom of the support pole.

[0034] Two sets of contact switches 3 are spaced apart along the height of the upright pole 5. The limiting device also includes a clamp 9, which is mounted on the side wall of the climbing equipment 10. The pole 5 is connected to the clamp 9, and the contact switches 3 are mounted on the end surface of the pole 5 surrounded by the clamp 9.

[0035] After the height and location of the pole 5 are determined, the installation positions of two sets of contact switches 3 and clamps 9 are determined on the sidewalls of the work platform of the aerial work equipment 10. The two sets of contact switches 3 remain vertically arranged, contacting different parts of the upright pole 5. When the pole 5 is in the upright position, the angle between the support rod and the pole 5 is 45 degrees, and the pole 5 and the bottom of the support rod are on the same horizontal line. This verifies that the pole 5 is absolutely vertical, avoiding safety accidents caused by the tilted installation of the pole 5, which may cause the actual height of the limiter 6 to be lower than the designed height.

[0036] When the climbing operation equipment 10 reaches a critical height, the limiter 6 transmits a signal to the motor controller 11 of the climbing operation equipment 10, and the motor controller 11 stops the climbing operation equipment 10 from continuing to rise to ensure the safety of the operation.

[0037] In addition, the vertical rod 5 is connected to the support rod to form a triangular stable structure, which ensures the stability of the limiter 6. When the limiter 6 is not needed, the foldable bracket is folded to the position shown in FIG. Figure 3 The state shown is shown, and the upright pole 5 is rotated to a horizontal state or below the top of the working platform of the climbing work equipment 10, so as to prevent the limiter 6 from being bumped when the climbing work equipment 10 moves, and also to prevent the limiter 6 from being too high and affecting the passage of the climbing work equipment 10.

[0038] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
