Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a pier foundation bridge construction platform. Background Art

[0002] After the existing bridge pier construction, scaffolding is often used to build a construction platform. Workers stand on the temporary scaffolding to work. The number of people required for construction is relatively limited, and there are certain safety hazards in the erection of the scaffolding. The installation and removal of the scaffolding take a long time, which seriously affects the efficiency and cost of the pier construction. In order to save installation and removal time, large crane equipment is often used in construction, but the use of cranes will not only increase the construction cost, but also be easily restricted by site factors, which is very inconvenient; the existing construction uses traditional aerial work methods such as hanging baskets, which are convenient for installation and removal and are less affected by the site, but the ropes and hanging baskets are greatly affected by the horizontal direction. In the case of strong winds, it may even cause the hanging basket to shake or flip, which is very unsafe and poses a great safety hazard.

[0003] Therefore, a pier foundation bridge construction platform is proposed. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a pier foundation bridge construction platform.

[0005] To achieve the above-mentioned purpose, the utility model provides a pier foundation bridge construction platform, comprising: a lifting assembly fixedly connected to both sides of the top of the pier foundation, the output end of the lifting assembly is fixedly connected to a steel cable, the end of the steel cable away from the lifting assembly is fixedly connected to an operating platform, and the operating platform is arranged around the pier foundation;

[0006] The operating platform comprises a bottom plate, the bottom plate is provided with a groove on the inner bottom surface close to the pier foundation, and the inner wall of the groove is circumferentially fixed with a plurality of cross-arranged fixing components and sliding components;

[0007] The sliding assembly includes a damping rod fixedly connected to the inner wall of the groove, a baffle plate fixedly connected to the movable end of the damping rod, a spring sleeved on the outer side of the damping rod, one end of the spring abuts against the baffle plate, and the other end abuts against the inner wall of the groove, a roller bracket fixedly connected to a side of the baffle plate away from the spring, a roller fixedly mounted on the roller bracket, and the roller abuts against the side wall of the pier foundation.

[0008] Preferably, the fixing assembly comprises an air pump telescopic rod, one end of the air pump telescopic rod is fixedly connected to the inner wall of the groove, and the other end is fixedly connected to a rubber pad.

[0009] Preferably, the operating platform also includes a fence fixedly connected to the four sides of the base plate, the fence includes a plurality of cross bars arranged above the edge of the base plate, the cross bars and the edge of the base plate are connected by a plurality of vertical bars to form a plurality of rectangular frames; the cross bars on both sides of the fence are fixedly connected to the ends of the steel cables at relative positions.

[0010] Preferably, an inclined reinforcing rod is fixed in each rectangular frame.

[0011] Preferably, the lifting assembly includes a winding box, a winding roller is rotatably connected inside the winding box, a motor is fixedly connected outside the winding box, and the motor is rotatably connected to the winding roller.

[0012] Preferably, the winding box is fixed to a mounting plate, and the mounting plate is fixed to the top of the pier foundation by bolts; one end of the mounting plate extends out of the top surface of the pier foundation and is fixed to a fixed pulley, and the steel cable is wound around the fixed pulley.

[0015] Compared with the prior art, the utility model has the following advantages and technical effects:

[0016] Before construction, construction workers stand on the bottom plate. The lifting assembly can lift and lower the operating platform by rolling up or releasing the steel cable, so as to transport the construction workers to a suitable height to carry out construction on the side or top of the pier foundation. During the lifting or lowering of the operating platform, the rollers in the sliding assembly are always in contact with the side wall of the pier foundation. Several sliding assemblies are arranged along the circumference of the pier foundation. When the operating platform is subjected to lateral external force, the operating platform shakes, and one end is close to the pier foundation, so that the rollers are subjected to the interaction force from the pier foundation. The rollers transmit the received force to the roller bracket, which is further transmitted to the baffle between the rollers, and then transmitted to the spring and the damping rod inside the spring by the baffle. The spring and the damping rod inside the spring can absorb and disperse the vibration energy of the operating platform, thereby reducing the swing amplitude and frequency of the platform and avoiding the shaking of the operating platform. The arrangement of multiple sliding assemblies around the circumference of the pier foundation can reduce the impact force of the outside world on the operating platform from any direction, reduce the risk of overturning and swinging of the operating platform, ensure the safety of workers, and improve the stability and comfort of workers' work. When the operating platform is raised or lowered, the rollers roll on the side walls of the pier foundation, changing the sliding friction between the sliding assembly and the side walls of the pier foundation into rolling friction, thereby reducing the wear of the sliding assembly.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-6As shown, this embodiment provides a pier foundation bridge construction platform, including: a lifting assembly 2 fixedly connected to both sides of the top of the pier foundation 1, a steel cable 201 fixedly connected to the output end of the lifting assembly 2, an end of the steel cable 201 away from the lifting assembly 2 is fixedly connected to an operating platform 3, and the operating platform 3 is arranged around the pier foundation 1;

[0028] The operating platform 3 includes a bottom plate 301, and a groove 302 is provided on the inner bottom surface of the bottom plate 301 close to the pier foundation 1. A plurality of cross-arranged fixing components 303 and sliding components 304 are fixedly connected to the inner wall of the groove 302 in a circumferential direction.

[0029] The sliding assembly 304 includes a damping rod 3041 fixedly connected to the inner wall of the groove 302, a baffle 3042 fixedly connected to the movable end of the damping rod 3041, a spring 3043 sleeved on the outer side of the damping rod 3041, one end of the spring 3043 abuts against the baffle 3042, and the other end abuts against the inner wall of the groove 302, a side of the baffle 3042 away from the spring 3043 is fixedly connected to a roller bracket 3044, a roller is fixedly installed on the roller bracket 3044, and the roller abuts against the side wall of the pier foundation 1.

[0030] Before construction, the construction workers stand on the base plate 301. The lifting component 2 can lift and lower the operating platform 3 by rolling up or releasing the steel cable 201, so as to transport the construction workers to a suitable height to carry out construction on the side or top of the pier foundation 1. During the lifting or lowering of the operating platform 3, the rollers in the sliding component 304 are always in contact with the side walls of the pier foundation 1. Several sliding components 304 are arranged circumferentially along the pier foundation 1. When the operating platform 3 is subjected to a lateral external force, the operating platform 3 shakes, and one end is close to the pier foundation 1, so that the rollers are subjected to the interaction force from the pier foundation 1. The rollers transmit the force to the roller bracket 3044, which is further transmitted to the baffle 3042 between the rollers, and then transmitted to the spring 3043 and the damping rod 3041 inside the spring 3043 by the baffle 3042. The spring 3043 and the damping rod 3041 inside the spring 3043 can absorb and disperse the vibration energy of the operating platform 3, thereby reducing the swing amplitude and frequency of the platform and avoiding shaking of the operating platform 3. The multiple sliding components 304 are arranged around the pier foundation 1 in a circumferential direction to reduce the impact force of the outside world on the operating platform 3 from any direction, reduce the risk of overturning and swinging of the operating platform 3, ensure the safety of workers, and improve the working stability and comfort of workers. When the operating platform 3 rises or falls, the roller rolls on the side wall of the pier foundation 1, and the sliding friction between the sliding components 304 and the side wall of the pier foundation 1 is converted into rolling friction, thereby reducing the wear of the sliding components 304.

[0031] Furthermore, the operating platform 3 can be manufactured according to the shape of the outer edge of the pier foundation 1, and can be in various shapes such as round, square, etc. In this embodiment, it is square.

[0032] According to a further optimized solution, the fixing assembly 303 includes an air pump telescopic rod 3031 , one end of which is fixedly connected to the inner wall of the groove 302 , and the other end of which is fixedly connected to a rubber pad 3032 .

[0033] The fixing assembly 303 is in a retracted state when the operating platform 3 rises or falls, that is, the air pump telescopic rod 3031 is in a retracted state. When the operating platform 3 reaches a determined position and the construction workers need to carry out construction at this height for a long time, the air pump telescopic rod 3031 is extended to make the rubber pad 3032 abut against the side wall of the pier foundation 1, so that there is a rigid support between the operating platform 3 and the pier foundation 1, thereby making the operating platform 3 more stable.

[0034] According to a further optimization scheme, the operating platform 3 also includes a fence 305 fixedly connected to the base plate 301, and the fence 305 includes a plurality of cross bars 3051 arranged above the edge of the base plate 301, and the cross bars 3051 and the edge of the base plate 301 are connected by a plurality of vertical bars 3052 to form a plurality of rectangular frames 3053; the cross bars 3051 on both sides of the fence 305 are fixedly connected to the ends of the steel cables 201 at relative positions.

[0035] The fence 305 surrounds the staff through the horizontal bar 3051 and the vertical bar 3052 to prevent the staff from falling from a high altitude;

[0036] Furthermore, the height of the fence 305 is preferably at the height of the human waist.

[0037] According to a further optimized solution, an inclined reinforcing rod 3054 is fixedly connected in each rectangular frame 3053 .

[0038] The reinforcing rod 3054 is tilted in the rectangular frame 3053 to increase the stability of the fence 305 .

[0039] According to a further optimized solution, the lifting component 2 includes a winding box 202 , a winding roller 203 is rotatably connected inside the winding box 202 , and a motor 204 is fixedly connected outside the winding box 202 , and the motor 204 is rotatably connected to the winding roller 203 .

[0040] The motor 204 can rotate forward and reverse. When the motor 204 rotates forward, it drives the winding roller 203 in the winding box 202 to rotate forward, so that the winding roller 203 reels the steel cable 201, thereby raising the operating platform 3; when the motor 204 rotates reversely, it drives the winding roller 203 in the winding box 202 to rotate reversely, so that the winding roller 203 unwinds the steel cable 201, thereby lowering the operating platform 3;

[0041] Furthermore, both motors 204 are electrically connected to a control system (not shown), and the control system simultaneously controls the forward and reverse rotation and stop of the two motors 204 .

[0042] To further optimize the solution, the winding box 202 is fixedly connected to the mounting plate 205 , and the mounting plate 205 is fixedly connected to the top of the pier foundation 1 by bolts; one end of the mounting plate 205 extends out of the top surface of the pier foundation 1 and is fixedly connected to a fixed pulley 206 , and the steel cable 201 is wound around the fixed pulley 206 .

[0043] The fixed pulley 206 is located outside the pier foundation 1 to guide the position of the steel cable 201 to avoid friction between the steel cable 201 and the edge of the pier foundation 1, thereby damaging the pier foundation 1 and avoiding the risk of breakage of the steel cable 201 due to wear, thereby affecting the safety of construction workers.

[0044] To further optimize the solution, a support rod 207 is fixedly connected to the bottom surface of one end of the mounting plate 205 extending out of the pier foundation 1. The support rod 207 is fixedly connected to the bottom end of the mounting plate 205 at an angle, and the end of the support rod 207 away from the mounting plate 205 is fixedly connected to the side wall of the pier foundation 1.

[0045] The support rod 207 shares the force exerted on the fixed pulley 206 with the pier foundation 1, and the pier foundation 1 supports the protruding mounting plate 205 to prevent the mounting plate 205 from breaking.

[0046] According to a further optimized solution, a cover plate 306 is detachably connected below the groove 302 , and the cover plate 306 is bolted to the bottom surface of the bottom plate 301 .

[0047] The cover plate 306 is detachable, which facilitates the installation and maintenance of the fixed component 303 and the sliding component 304 in the groove 302. At the same time, it isolates external impurities to a certain extent, prevents the fixed component 303 and the sliding component 304 from being damaged, and extends the service life of the equipment.
