Description

Technical Field

[0001] The utility model belongs to the technical field of suspension basket applications, and particularly relates to a movable suspended steel beam operation platform. Background Art

[0002] The application of steel structure construction in domestic construction projects is becoming more and more extensive, and the steel structure construction technology has basically developed maturely. During the construction of high-altitude steel structure connections, the suspended steel beam operation platform, as an important construction tool for bolt tightening and welding of horizontal members, is widely used in various forms of steel structure construction.

[0003] In recent years, with the development and progress of the times, people's requirements for buildings have become higher and higher, and the shapes of various buildings are becoming more and more unique. In order to meet the unique shapes of buildings, a large number of components with unique shapes such as steel structure skywalks and steel structure circular domes have emerged. Due to the complex structures of steel structure skywalks and steel structure circular domes, aerial splicing operations are often required during construction. When performing such operations, the traditional construction method is to fabricate hanging platforms such as cages on site for welding. However, due to the different sizes of steel beam members, it is necessary to fabricate various hanging platforms of different sizes, which affects the construction efficiency and cost. Content of the Utility Model

[0004] Aiming at the above problems in the prior art, the utility model aims to provide a movable suspended steel beam operation platform, which solves the problem that the existing hanging platform cannot be applied to steel beam members with different sizes.

[0005] In order to achieve the above utility model purpose, the technical scheme adopted by the utility model is as follows:

[0006] A movable suspended steel beam operation platform is provided, which includes a platform main body. A locking component for cooperating with the steel beam main body is arranged at the top of the platform main body, and the steel beam main body is an I-shaped steel section or an H-shaped steel section. The locking component includes two longitudinal fixed beams that are horizontally spaced and fixedly connected to the top of the platform main body. Two clamping blocks for locking and cooperating with the upper flange of the steel beam main body are arranged below each longitudinal fixed beam. The two clamping blocks move towards or away from each other simultaneously along the length direction of the longitudinal fixed beam, and the two clamping blocks are respectively located on both sides of the web of the steel beam main body.

[0007] The basic principle of the movable suspended steel beam operation platform is as follows: By arranging clamping blocks that move towards or away from each other simultaneously below the two longitudinal fixed beams, when it is necessary to fix the platform main body to steel beam main bodies with different sizes, the distance between the two clamping blocks can be adjusted to adapt to different steel beam main bodies, so as to realize the platform main body on steel beam main bodies with different sizes.

[0008] Further, as a specific implementation manner in which the clamping blocks move towards or away from each other simultaneously along the length direction of the longitudinal fixing beams, each longitudinal fixing beam has a hollow columnar structure. A limiting groove is provided along the length direction at the bottom of each longitudinal fixing beam. A threaded rod is rotatably arranged in each longitudinal fixing beam. Two threaded segments with opposite helix directions are symmetrically arranged on each threaded rod. The tops of the two clamping blocks below the longitudinal fixing beams pass through the limiting grooves and are respectively in threaded cooperation with the two threaded segments.

[0009] The two clamping blocks are respectively threadedly connected to the two threaded segments with opposite helix directions on the threaded rod. When the threaded rod rotates, since the limiting groove can restrict the rotational freedom of the clamping blocks, the rotational motion received by the clamping blocks is converted into a linear motion. The two clamping blocks move towards or away from each other simultaneously, realizing the clamping or loosening of the two clamping blocks, so as to achieve the technical effect of fixing or loosening the platform main body.

[0010] Further, as a specific implementation manner for driving the threaded rod to rotate around its own axis, a driving motor is provided at one end of each threaded rod, and the other end is rotatably connected to the inner wall of the longitudinal fixing beam. The two driving motors are respectively fixed inside the two longitudinal fixing beams. The output end of each driving motor is fixedly connected to the corresponding threaded rod and drives the threaded rod to rotate around its own axis. The two driving motors operate synchronously.

[0011] Further, as another specific implementation manner for driving the threaded rod to rotate around its own axis, a transmission wheel is provided at the free end of each longitudinal fixing beam. The two transmission wheels are connected by a transmission belt. One end of the threaded rod in each longitudinal fixing beam passes through the free end of the longitudinal fixing beam and is coaxially fixedly connected to the transmission wheel. A driving motor is provided inside one of the longitudinal fixing beams. The other end of the threaded rod in this longitudinal fixing beam is fixedly connected to the output end of the driving motor, and the driving motor drives the threaded rod to rotate around its own axis.

[0012] By providing transmission wheels at the free ends of the two longitudinal fixing beams and connecting the two transmission wheels by a transmission belt, one driving motor is used to drive the two longitudinal fixing beams to rotate synchronously, so as to achieve simultaneous control of the synchronous movement of the clamping blocks below the two longitudinal fixing beams.

[0013] Further, a pushing frame is arranged between the two longitudinal fixing beams. A moving wheel that contacts the upper end surface of the upper flange of the steel beam main body is arranged below the pushing frame. The sliding direction of the moving wheel is the same as the length direction of the steel beam main body.

[0014] Furthermore, the push frame includes two push beams arranged at intervals, the lower end faces of the two push beams are respectively welded and fixed to the upper end faces of the two longitudinal fixed beams; the length direction of the push beam is perpendicular to the length direction of the longitudinal fixed beam, the lower end face of the push beam is provided with a moving wheel, and there is a gap between the upper end face of the longitudinal fixed beam and the upper end face of the upper wing plate of the steel beam body. The setting of the moving wheel and the gap converts the sliding friction into rolling friction when the entire movable suspended steel beam operating platform is moved, and the movable suspended steel beam operating platform is pushed more labor-savingly, thereby improving the convenience during use.

[0015] When the platform body needs to be moved, the driving motor is first started to drive the two threaded rods to rotate around their own axes. The two rotating threaded rods drive the clamps to move outward and away from each other at the same time until the ends of the horizontal sections of the clamps are separated from the side surfaces of the web of the steel beam body. The driving motor stops rotating and then pushes the pushing frame. The pushing frame drives the locking assembly and the platform body to move along the length direction of the steel beam body until they reach the appropriate position. The driving motor is then started again to rotate in the opposite direction, driving the clamps to move toward each other until the ends of the horizontal sections of the two clamps are clamped and fixed to the two side surfaces of the web of the steel beam body, thereby fixing the position of the platform body.

[0016] Furthermore, as a specific setting method of the clamping block, each clamping block has an "L" structure, the top of the vertical section of the clamping block passes through the limit groove and cooperates with the threaded rod, and the upper end surface of the horizontal section of the clamping block contacts the lower end surface of the upper wing plate of the steel beam body.

[0017] The beneficial effects of the utility model are as follows: 1. A movable suspended steel beam operating platform of the utility model is provided with clamping blocks that move toward or away from each other at the same time under the two longitudinal fixed beams. When it is necessary to fix the platform body to steel beam bodies of different sizes, the distance between the two clamping blocks can be adjusted to adapt to different steel beam bodies, so that the platform body can be placed on steel beam bodies of different sizes, thereby improving the applicability and solving the problem that the suspended platform in the prior art cannot be applied to steel beams of different sizes.

[0018] 2. The utility model provides a movable suspended steel beam operating platform. When the platform body needs to be moved, the position of the platform body can be quickly adjusted through the pushing frame, so that the platform body can move freely on the steel beam body, thereby improving the convenience during use.

[0027] The two clamping blocks 5 are respectively threadedly connected to two thread segments with opposite helix directions on the threaded rod 6. When the threaded rod 6 rotates, since the limiting groove can restrict the rotational freedom of the clamping block 5, the clamping block 5 converts the received rotational motion into linear motion, and the two clamping blocks 5 move towards or away from each other simultaneously, realizing the clamping or loosening of the two clamping blocks 5, so as to achieve the technical effect of fixing or loosening the platform main body 11.

[0030] By providing the transmission wheels 8 at the free ends of the two longitudinal fixed beams 4 and drivingly connecting the two transmission wheels 8 by the transmission belt 9, one driving motor 7 is used to drive the two longitudinal fixed beams 4 to rotate synchronously, so as to achieve simultaneous control of the synchronous movement of the clamping blocks 5 below the two longitudinal fixed beams 4.

[0031] Preferably but not limitedly, a push frame 10 is provided between the two longitudinal fixed beams 4, and a moving wheel 11 in contact with the upper end surface of the upper flange of the steel beam main body 2 is provided below the push frame 10, and the sliding direction of the moving wheel 11 is the same as the length direction of the steel beam main body 2.
