Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a movable scaffolding structure for bridge construction. Background Technique

[0002] Scaffolding is various supports erected at the construction site for workers to operate and solve vertical and horizontal transportation problems. It is mainly used for workers to work up and down, or for enclosing safety nets on the periphery and installing components at high altitudes. Scaffolding is used during building construction. Generally, it consists of an installation frame and a support plate at the top. Most of the support plates at the top of the existing scaffolding are fixed to the top of the support frame through fixing parts such as bolts, so as to facilitate workers to stand on the support plate to work;

[0003] The Chinese utility model with the patent number CN202211314284.2 discloses a scaffolding that is easy to assemble, including support legs, and two support rods are fixedly connected between two adjacent support legs; a support plate installation mechanism is arranged between multiple support legs; the support plate installation mechanism includes a first support plate, a second support plate, a positioning component and a support component. The first support plate and the second support plate are both rotatably inserted through adjacent two support legs through rotating shafts, the first support plate and the second support plate are rotatably connected through hinges, two chutes are opened at the bottom ends of the first support plate and the second support plate, the positioning component is located inside the chutes, and multiple positioning components are respectively arranged on both sides of the first support plate and the second support plate.

[0004] However, during bridge construction, this scaffolding only considers easy assembly and does not consider the problem of the required height in actual use. It is not convenient to increase the height. Moreover, although the background technology mentions protection, it does not consider the safety of workers during high-altitude operations and does not have any protective measures; and this scaffolding only sets universal wheels at the bottom. The simple setting of universal wheels may cause the scaffolding to shake, and does not consider the stability of the scaffolding, and does not consider the safety hazards of workers in a comprehensive manner.

[0005] Therefore, we propose a movable scaffolding structure for bridge construction to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a movable scaffolding for building construction to solve the problems raised in the above background technology.

[0007] To achieve the above object, the utility model provides the following technical solution: A movable scaffolding structure for bridge construction, comprising a cross plate, a plurality of vertical rods, a plurality of horizontal rods, a plurality of second horizontal rods, a plurality of footrests, a plurality of pin blocks and a plurality of pins. Four vertical rod connection blocks are fixedly connected to the side wall of the vertical rod, and a vertical rod connection head is fixedly connected to the top. A vertical rod pin hole is horizontally opened at the bottom end of the vertical rod, and a vertical rod through hole is opened at the bottom. A vertical rod connection block pin hole is opened in the vertical rod connection block, and a vertical rod connection head pin hole is opened in the vertical rod connection head;

[0008] Four vertical rods are fixedly connected to the four corners of the top surface of the cross plate. The vertical rod through holes of the remaining vertical rods are fixedly sleeved on the vertical rod connection heads of the lower vertical rods. The vertical rod through holes are fixedly sleeved on the vertical rod connection heads through four pin blocks respectively. The pin blocks are inserted into the vertical rod through holes and the vertical rod connection head pin holes. The vertical rod connection blocks at the upper end on one side of the vertical rod are fixedly sleeved with two cross rod connection blocks through pin blocks, and the upper and lower vertical rod connection blocks on the other side are fixedly sleeved with two second cross rod connection blocks through pin blocks respectively.

[0009] Preferably: Two cross rod connection blocks are fixedly connected to both ends of the cross rod. Four cross rod pin holes are opened on the surface of the cross rod. A cross rod connection block pin hole is opened in the middle of the cross rod connection block. The two cross rods are located between the upper ends of the four vertical rods. The pin blocks are inserted into the cross rod connection block pin holes and the vertical rod connection block pin holes.

[0010] Preferably: Two second cross rod connection blocks are fixedly connected to both side walls of the second cross rod. A second cross rod connection block pin hole is opened in the middle of the second cross rod connection block. The four second cross rods are located between the four vertical rods. The pin blocks are inserted into the second cross rod connection block pin holes and the vertical rod connection block pin holes.

[0011] Preferably: Two footrest hooks are fixedly connected to both side walls of the footrest respectively. Footrest guards are fixedly connected to both sides of the upper surface of the footrest. A footrest mesh is fixedly connected to the inner side wall of the footrest guard. A hook pin hole is opened at the end of the footrest hook away from the footrest. The two footrests are fixedly sleeved on the two uppermost cross rods through four pin blocks respectively. The pin blocks are inserted into the hook pin holes and the cross rod pin holes. The height of the footrest guard can be set to 110 cm.

[0012] Preferably: Four threaded through holes are vertically opened at the edge of the cross plate. Four threaded rods are threadedly connected to the four threaded through holes. A handle is fixedly connected to the top of the threaded rod. A counterweight block is fixedly connected to the bottom of the threaded rod. A counterweight block through hole is opened in the counterweight block. The bottom surface of the counterweight block and the orifice of the threaded through hole are made of damping material. Four universal wheels are fixedly connected to the bottom of the four sides of the cross plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: During use, first install it. The cross bar is fixedly sleeved with four vertical bars respectively through pin blocks, and the cross bar is fixedly sleeved with two foot pedals respectively through pin blocks. The second cross bar is fixedly sleeved with the upper and lower ends of four vertical bars respectively through pin blocks, and the cross bar is fixedly sleeved with two foot pedals respectively through pin blocks. The setting of the two second cross bars not only ensures stability to a certain extent, but also can be used as a ladder;

[0014] When the height is insufficient, repeat the above installation steps. Stand on the foot pedal. A unit composed of four vertical bars, a cross bar and a second cross bar can be stacked and heightened. When heightening, only need to connect the vertical bars to each other and insert the pin blocks; This avoids the problem that the staff cannot reach the working location due to the excessive height of the bridge. The unevenness on the surface of the foot pedal can increase the friction. The height of the foot pedal guardrail is 110 cm. The height design of 110 cm can exceed the average waist height of Chinese men, ensuring a certain degree of protection. The setting of the foot pedal guard net is a further supplement to the protection, which can ensure the safety of the staff during high-altitude operation to a certain extent;

[0015] When it is necessary to fix the position, lock the universal wheels, turn the swing hand counterclockwise, the counterweight block descends horizontally to the ground, and then fix it multiple times by inserting a pin into the through hole of the counterweight block and nailing it into the ground. The bottom of the counterweight block is made of damping material to prevent vibration. At this time, the scaffolding is fixed, greatly reducing the sense of vibration and no longer moving;

[0016] When it is necessary to move, take out the pin on the through hole of the counterweight block, turn the handle clockwise, the threaded rod fixedly connected to the bottom of the handle rotates, the threaded rod fixedly connected to the bottom of the counterweight block rotates, rises horizontally away from the ground, and then open the universal wheels for convenient movement.
