A type of anti-fall and anti-overturning roof support boot for building construction machines

Abstract

This invention discloses a top-lifting support shoe for a building construction machine to prevent fall and overturning, comprising: a support frame, the support frame including a front support plate and a rear support plate; a connecting part, the connecting part being disposed on the support frame; and two sets of support blocks. In this invention, during the lifting process of the support shoe, when the support blocks are rotated under pressure, the fixed bevel gear inside is fixed relative to the support blocks, while the driven bevel gear rotates around the fixed bevel gear. When the driven bevel gear rotates, due to its meshing with the fixed bevel gear, the driven bevel gear also rotates, thereby driving the moving ring to move. When the moving ring moves, it can drive the slider to translate. The end of the slider is provided with a support block. The support block, under the action of the slider, can extend and retract on the side of the support blocks, achieving the effect that the support block can retract when the support blocks rotate and retract, and expand to provide support when the support blocks expand.

Description

Technical Field

[0001] This invention relates to the field of building construction machine structure technology, and in particular to a building construction machine top lifting support shoe to prevent fall and overturning. Background Technology

[0002] The lifting support shoe of a building construction machine is a component used in the power system of the machine. Its main function is to cooperate with the climbing frame and support to convert the extension and retraction of the hydraulic cylinder into the displacement of the entire building construction machine, thereby achieving the purpose of lifting.

[0003] Currently, the lifting support shoes of building construction machines do not have anti-fall and anti-overturn measures. This makes the building construction machine prone to overturning during operation if there is concrete or other debris between the support shoes and the climbing frame. There is a risk of falling if personnel are not supervised in time. There is room for improvement. Therefore, a building construction machine lifting support shoe with anti-fall and overturn measures is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a building construction machine top support boot that prevents falls and overturning.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a building construction machine top lifting support shoe for preventing fall and overturning, comprising:

[0006] A support frame, the support frame including a front support plate and a rear support plate;

[0007] The connecting part is disposed on the support frame;

[0008] The support blocks are arranged in two sets and are rotatably mounted inside the support frame. The support blocks are used to rotate to avoid obstacles when they encounter obstacles on their top.

[0009] An auxiliary block is disposed within a support block at one end of the support block away from the support frame, and an extension component for ejecting the auxiliary block is provided within the support block.

[0010] The extension assembly includes a fixed bevel gear fixedly connected to the rear support plate and extending into the support block, a slider slidably disposed inside the support block, and a first lead screw rotatably disposed inside the support block. The end of the first lead screw near the fixed bevel gear has a driven bevel gear meshing with the fixed bevel gear. The slider has a movable ring threadedly connected to the first lead screw. A support block is provided at the end of the slider to allow the support block to reset and unfold as the support block rotates.

[0011] A reset mechanism is provided on the support frame and fixedly connected to the support block, which is used to pull the support block to reset and unfold.

[0012] Furthermore, the support block is provided with a rotating shaft that is rotatably connected to the front support plate, and the rotating shaft is coaxially arranged with the fixed bevel gear.

[0013] Furthermore, the reset mechanism includes an adjusting screw and an adjusting knob sleeved on the outside of the adjusting screw, and a connecting collar is sleeved on the adjusting knob;

[0014] The reset mechanism also includes a connecting shaft fixedly connected to the support block, and a reset spring is provided between the connecting shaft and the connecting sleeve. The reset spring is used to pull the support block to reset and unfold.

[0015] Furthermore, the number of support blocks is two sets, and the support block is provided with an anti-collision inclined block;

[0016] Both sets of support blocks have inclined surfaces on opposite sides, and the two sides of the abutting inclined blocks have abutting inclined surfaces corresponding to the inclined surfaces;

[0017] The support block has an extension slot corresponding to the support block.

[0018] Furthermore, the front support plate and the rear support plate in the support frame are integrally welded to the connecting part;

[0019] The connecting part includes two sets of connecting lugs and a receiving shaft disposed between the two sets of connecting lugs.

[0020] Furthermore, an extension plate is provided on the connecting shaft, and connecting rings are provided on both sides of the connecting sleeve and on the extension plate for connecting the return spring.

[0021] Furthermore, the support block is in the shape of a right triangle, and an arc is provided at the right angle of the support block, the center of which coincides with the center point of the connecting shaft.

[0022] Furthermore, the fixed bevel gear and the driven bevel gear are arranged perpendicularly, and the driven bevel gear meshes with the fixed bevel gear and rotates around the fixed bevel gear as the center.

[0023] The beneficial effects of this invention are reflected in:

[0024] In this invention, during the upward movement of the support shoe, when the support block rotates under pressure, the fixed bevel gear inside is fixed relative to the support block, while the driven bevel gear rotates around the fixed bevel gear. When the driven bevel gear rotates, due to its meshing with the fixed bevel gear, the driven bevel gear also rotates, thereby driving the moving ring to move. When the moving ring moves, it can drive the slider to translate. The end of the slider is provided with a support block. The support block is affected by the slider, so it can extend and retract on the side of the support block. This achieves the effect that the support block can retract when the support block rotates and retracts, and expand to provide support when the support block expands. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-4 This invention discloses a building construction machine top lifting support shoe to prevent fall and overturning, comprising:

[0037] The support frame 1 includes a front support plate 11 and a rear support plate 12;

[0038] Connecting part 2, which is disposed on the support frame 1;

[0039] Support block 3, there are two sets of support blocks 3, which are rotatably installed in the support frame 1. The top of the support block 3 is provided with a contact slope, so that the support block 3 can rotate to avoid the obstacle after encountering an obstacle on its top.

[0040] Auxiliary block 4 is disposed in the support block 3. The auxiliary block 4 is disposed at the end of the support block 3 away from the support frame 1. An extension component for pushing out the auxiliary block (4) is disposed in the support block 3.

[0041] The extension assembly includes a fixed bevel gear 33 fixedly connected to the rear support plate 12 and extending into the support block 3; a slider 35 slidably disposed within the support block 3; and a first lead screw 31 rotatably disposed within the support block 3. The end of the first lead screw 31 near the fixed bevel gear 33 is provided with a driven bevel gear 34 meshing with the fixed bevel gear 33. The slider 35 is provided with a movable ring 32 threadedly connected to the first lead screw 31. The end of the slider 35 is provided with a support block 41, which allows the support block 41 to extend and retract with the rotation of the support block 3. It should be noted that the fixed bevel gear 33 and the driven bevel gear 34 are arranged perpendicularly, and the driven bevel gear 34 meshes with the fixed bevel gear 33 and rotates about the fixed bevel gear 33 as its center.

[0042] The reset mechanism 5 is mounted on the support frame 1 and fixedly connected to the support block 3, and is used to pull the support block 3 to reset and unfold.

[0043] In this application, it should be noted that during use, the support shoe needs to rise and climb within the climbing frame. During the rising process of the support shoe, the support blocks 3 on both sides will contact and retract with the buckles inside the climbing frame. After passing the buckles, the two sets of support blocks 3 will be re-expanded under the action of the reset mechanism 5 and pressed against the buckles to achieve the climbing effect. In order to ensure the stability during the climbing process and improve the contact surface between the support shoe and the climbing frame, an auxiliary block 4 is provided on the side of the support block 3 to support the side of the support block 3.

[0044] Specifically, when the support block 3 is rotated under pressure, the fixed bevel gear 33 inside it is fixed relative to the support block 3, while the driven bevel gear 34 rotates around the fixed bevel gear 33. When the driven bevel gear 34 rotates, due to its meshing with the fixed bevel gear 33, the driven bevel gear 34 will also rotate, thereby driving the moving ring 32 to move. When the moving ring 32 moves, it can drive the slider 35 to translate. The end of the slider 35 is provided with a support block 41. The support block 41 is extended and retracted on the side of the support block 3 by the action of the slider 35. This achieves the effect that the support block 41 can retract when the support block 3 rotates and retracts, and expand when the support block 3 expands to provide support.

[0045] It should be noted that the support block 3 is provided with a rotating shaft that is rotatably connected to the front support plate 11. The rotating shaft is coaxially arranged with the fixed bevel gear 33 so as to synchronize the rotation of the support block 3 to the driven bevel gear 34, so that it can generate relative movement with the fixed bevel gear 33.

[0046] In this application, the reset mechanism 5 includes an adjusting screw 52 and an adjusting knob 55 sleeved on the outside of the adjusting screw 52, ​​and a connecting collar 53 is sleeved on the adjusting knob 55;

[0047] The reset mechanism 5 also includes a connecting shaft 51 fixedly connected to the support block 3. A reset spring 54 is provided between the connecting shaft 51 and the connecting sleeve 53. The reset spring 54 is used to pull the support block 3 to reset and unfold.

[0048] With the above structural configuration, when the equipment is in use, after the support block 3 is rotated under pressure, it can drive the return spring 54 to stretch. The return spring 54 can pull the support block 3 to reset after the pressure point of the support block 3 disappears, thereby enabling climbing.

[0049] Furthermore, by setting an adjustment knob 55, and having a connecting collar 53 attached to the adjustment knob 55, the position of the connecting collar 53 can be adjusted by rotating the adjustment knob 55, thereby achieving the purpose of adjusting the tightness of the return spring 54.

[0050] like Figure 3-4 As shown, there are two sets of support blocks 41, and the support block 3 is provided with an abutting inclined block 42.

[0051] Both sets of support blocks 41 have inclined surfaces on opposite sides, and the abutting inclined blocks 42 have abutting inclined surfaces on both sides corresponding to the inclined surfaces;

[0052] The support block 3 has an extension groove corresponding to the support block 41.

[0053] With the above structural arrangement, when the support block 41 moves with the slider 35, the inclined surfaces of the two sets of support blocks 41 can contact the inclined surfaces of the contacting inclined block 42, thereby pushing the support blocks 41 to separate and expand, achieving the effect of unfolding.

[0054] It should be noted that the support block 41 and the abutting inclined block 42 are common extended structures, and other extended structures may be used instead in this application.

[0055] In this application, the front support plate 11 and the rear support plate 12 of the support frame 1 are integrally welded to the connecting part 2;

[0056] The connecting part 2 includes two sets of connecting lugs and a receiving shaft disposed between the two sets of connecting lugs. The connecting part 2 is used to connect the hydraulic components of the building construction machine to achieve climbing.

[0057] It should be noted that an extension plate is provided on the connecting shaft 51, and connecting rings are provided on both sides of the connecting sleeve 53 and on the extension plate for connecting the return spring 54.

[0058] In this application, the support block 3 is a right triangle with an arc at the right angle. The center of the arc coincides with the center point of the connecting shaft 51. When the two sets of support blocks 3 are under load, the opposite sides of the two sets of support blocks 3 are in contact with each other, thereby playing a supporting role.

[0059] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0060] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0061] Additionally, "multiple" refers to two or more.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
