Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, and in particular to a protective device for bridge construction. Background Technology
[0002] Currently, in the field of bridge construction, the use of protective devices is crucial for ensuring the safety of construction workers and improving construction efficiency. Traditional road and bridge construction protective devices are often simply designed and have limited functions, making it difficult to adapt to the construction needs of bridges with different thicknesses and shapes. During construction, workers often need to frequently move construction equipment, and traditional protective devices, lacking effective translation mechanisms, make it difficult to move the equipment, greatly reducing construction efficiency.
[0003] Traditional protective devices also have shortcomings in terms of stability. Due to the lack of effective support and fixing structure, the protective devices are prone to shaking or tilting during use, which poses safety hazards to construction workers, especially when working at heights.
[0004] To address the aforementioned issues, while some improved protective devices have emerged in the existing technology, these devices are often complex in structure, cumbersome in operation, and lack adaptability. Therefore, there is an urgent need for a protective device for bridge construction that can adapt to different bridge thicknesses, has a translation mechanism, and is highly stable, in order to improve construction efficiency and ensure the safety of construction personnel.
[0005] To address these issues, we propose a protective device for bridge construction. This device can be installed on bridges of varying thicknesses and has a horizontally movable function, facilitating high-altitude work by construction workers on the bridge sidewalls. Utility Model Content
[0006] The purpose of this utility model is to solve the problems existing in the prior art and to propose a protective device for bridge construction.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A protective device for bridge construction includes: a protective construction frame, a construction chamber fixedly installed on one side of the bottom of the protective construction frame, a top frame installed on one side of the top of the protective construction frame, and a construction translation mechanism installed on the inner side of both the protective construction frame and the top frame;
[0009] The construction translation mechanism includes three sets of equidistant adjustment holes on one side of the top of the protective construction frame, three sets of equidistant adjustment frames fixedly installed on one side of the top of the top frame, reinforcement plates fixedly installed on both sides of the middle of the protective construction frame, first translation seats fixedly installed on both sides of the two sets of reinforcement plates, first translation rollers rotatably installed inside each set of first translation seats, second translation seats fixedly installed at both ends of the inner side of the top frame, and second translation rollers rotatably installed inside the two sets of second translation seats.
[0010] Preferably, the three sets of adjustment frames are movably connected to the three sets of adjustment holes respectively. The first translation roller and the second translation roller of each set move horizontally. The multiple sets of first translation rollers and second translation rollers correspond to the side wall of the bridge respectively. A screw hole is opened on one side of the middle part of the protective construction frame. A positioning rod is installed in the screw hole with internal thread. A rubber pad is fixedly installed at the other end of the positioning rod.
[0011] Preferably, the top of the protective construction frame has three sets of equally spaced screw holes, and each set of screw holes is threaded with a positioning bolt. The three sets of positioning bolts correspond to three sets of adjustment frames, which can fix the adjustment frames.
[0012] Preferably, a top seat is fixedly installed on the inner side of the top of the protective construction frame, and multiple sets of equally spaced support rollers are rotatably installed on the inner side of the top seat. The multiple sets of support rollers correspond to the top of the bridge, so that the protective construction frame and the top of the bridge can move arbitrarily in the horizontal direction.
[0013] Preferably, limit rings are fixedly installed on both sides of the bottom of the top frame, and crossbars are movably installed in the two sets of limit rings. Both sides of the crossbars are fixedly installed to the side wall of the bridge by fasteners, which can support the top frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention precisely controls the length of the adjusting frames within three sets of adjusting holes according to different bridge thicknesses, ensuring that the distance between the protective construction frame and the top of the top frame corresponds to the bridge thickness. After the protective construction frame and the top frame are installed on the top of the bridge, multiple sets of first translation rollers installed on the protective construction frame and two sets of second translation rollers installed on the top frame are used. When the operator completes construction on one section of the bridge sidewall, the operator can push the protective construction frame and the top frame, causing them to move horizontally along with the first and second translation rollers, greatly improving the operator's construction efficiency on the bridge.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-3 A protective device for bridge construction includes: a protective construction frame 1, a construction chamber 12 fixedly installed on one side of the bottom of the protective construction frame 1, a top frame 11 installed on one side of the top of the protective construction frame 1, and a construction translation mechanism installed on the inner side of both the protective construction frame 1 and the top frame 11.
[0024] The construction translation mechanism includes three sets of equidistantly distributed adjustment holes 2 on one side of the top of the protective construction frame 1; three sets of equidistantly distributed adjustment frames 21 fixedly installed on one side of the top of the top frame 11; reinforcement plates 22 fixedly installed on both sides of the middle of the protective construction frame 1; first translation seats 23 fixedly installed on both sides of the two sets of reinforcement plates 22; first translation rollers 24 rotatably installed inside each set of first translation seats 23; second translation seats 25 fixedly installed at both ends of the inner side of the top frame 11; and second translation rollers 26 rotatably installed inside the two sets of second translation seats 25. The three sets of adjustment frames 21 are movably connected to the three sets of adjustment holes 2 respectively. Each set of first translation rollers 24 and second translation rollers 26 moves horizontally. The shifting roller 24 and the second shifting roller 26 correspond to the bridge sidewalls respectively. By precisely controlling the length of the adjusting frame 21 in the three sets of adjusting holes 2 according to different bridge thicknesses, the distance between the top of the protective construction frame 1 and the top frame 11 corresponds to the bridge thickness. After the protective construction frame 1 and the top frame 11 are installed on the top of the bridge, the multiple sets of first shifting rollers 24 installed on the protective construction frame 1 and the two sets of second shifting rollers 26 installed on the top frame 11 can be used to push the protective construction frame 1 and the top frame 11 when the operator completes the construction of one section of the bridge sidewall. This allows the protective construction frame 1 and the top frame 11 to move horizontally along with the first shifting rollers 24 and the second shifting rollers 26, greatly improving the operator's construction efficiency on the bridge.
[0025] Furthermore, a screw hole is provided on one side of the middle of the protective construction frame 1, and a positioning rod 27 is installed in the screw hole. A rubber pad is fixedly installed on the other end of the positioning rod 27. When the operator is in the construction chamber 12 at the bottom of the protective construction frame 1 and can carry out construction on the bridge side wall, the positioning rod 27 in the screw hole can be screwed in, so that the rubber pad installed on the other end of the positioning rod 27 fits against the bridge side wall, and the construction chamber 12 is firmly fixed to one side of the bridge side wall.
[0026] Furthermore, limiting rings 32 are fixedly installed on both sides of the bottom of the top frame 11. A crossbar 33 is movably installed within each of the two sets of limiting rings 32. Both sides of the crossbar 33 are fixed to the bridge sidewall via fasteners, providing support for the top frame 11. After the protective construction frame 1 and the top frame 11 are installed on the top of the bridge sidewall, the operator can insert the crossbar 33 into the limiting rings 32 on both sides of the bottom of the top frame 11 and install fasteners at both ends of the bridge sidewall using expansion bolts. After the two sets of fasteners are installed on both sides of the crossbar 33, the bottom of the top frame 11 is firmly fixed by the crossbar 33. The sliding connection between the limiting rings 32 and the crossbar 33 ensures that the protective construction frame 1 and the top frame 11 can move horizontally along the direction of the crossbar 33, further improving the safety of the device.
[0027] Furthermore, a sliding ring 34 is slidably installed at one end of the crossbar 33, a hoisting rope 35 is fixedly installed on the side wall of the sliding ring 34, and a safety rope is fixedly installed at the other end of the hoisting rope 35, which further improves the safety of construction personnel. When the operator is working in the construction chamber 12 at the bottom of the protective construction frame 1, he / she can wear the safety rope at the other end of the hoisting rope 35 at the same time, which further improves the safety of construction personnel.
[0028] Furthermore, a top seat 3 is fixedly installed on the inner side of the top of the protective construction frame 1. Multiple sets of equally spaced support rollers 31 are rotatably installed on the inner side of the top seat 3. The multiple sets of support rollers 31 correspond to the top of the bridge, allowing the protective construction frame 1 and the top of the bridge to move arbitrarily in the horizontal direction. When the protective construction frame 1 and the top frame 11 are installed on the top of the bridge, the top seat 3 installed on the top of the protective construction frame 1, with multiple sets of support rollers 31 rotatably installed inside the top seat 3, can make the top of the protective construction frame 1 move horizontally along the top side of the bridge.
[0029] Furthermore, the top of the protective construction frame 1 has three sets of equally spaced screw holes, and each set of screw holes is threaded with a positioning bolt 13. The three sets of positioning bolts 13 correspond to the three sets of adjustment frames 21, which can fix the adjustment frames 21. When the operator accurately controls the length of the adjustment frame 21 in the three sets of adjustment holes 2 according to different bridge thicknesses, the three sets of positioning frames can be firmly fixed by tightening the positioning bolts 13 in the three sets of screw holes.
[0030] In use, the top frame 11 is first installed on top of the protective construction frame 1, and the protective construction frame 1 and the top of the top frame 11 are then snapped together on the top of the bridge. The operator can then move to the construction chamber 12 at the bottom of the protective construction frame 1 to perform construction on the bridge sidewall. Simultaneously, the operator can precisely control the length of the adjusting frames 21 within the three sets of adjusting holes 2 according to different bridge thicknesses, ensuring that the distance between the top of the protective construction frame 1 and the top of the top frame 11 corresponds to the bridge thickness. After the protective construction frame 1 and the top frame 11 are installed on the top of the bridge, the multiple sets of first translation rollers 24 installed on the protective construction frame 1 and the two sets of second translation rollers 26 installed on the top frame 11 are used. When the operator completes construction on one section of the bridge sidewall, the operator can push the protective construction frame 1 and the top frame 11 to move them together. 1. Following the horizontal movement of the first translation roller 24 and the second translation roller 26, the operator's construction efficiency on the bridge is greatly improved. At the same time, the limit rings 32 are fixedly installed on both sides of the bottom of the top frame 11, and the crossbars 33 are movably installed in the two sets of limit rings 32. After the protective construction frame 1 and the top frame 11 are installed on the top of the bridge side wall, the operator can insert the crossbars 33 into the limit rings 32 on both sides of the bottom of the top frame 11, and install the fixing parts at both ends of the bridge side wall with expansion bolts. After the two sets of fixing parts are installed on both sides of the crossbars 33, it can be ensured that the bottom of the top frame 11 is firmly fixed by the crossbars 33. With the limit rings 32 and the crossbars 33 slidingly connected, the protective construction frame 1 and the top frame 11 can move horizontally along the direction of the crossbars 33, which further improves the safety of the device.
