[0032] Example

[0033] See also Figures 1 to 11 In this embodiment, a multifunctional construction spanning frame is provided, including a workbench 2 and a base 1. The workbench 2 is arranged on the top of the base 1, wherein the base 1 includes a bottom plate 101, and a movable leg 102 is installed at the bottom of the bottom plate 101. The movable leg 102 can facilitate the movement and arrangement of the entire spanning frame, and a multi-stage hydraulic rod 105 is arranged in the middle of the bottom plate 101, and telescopic limit rods 106 are arranged on the left and right sides of the multi-stage hydraulic rod 105. A top seat 107 is arranged on the top of the telescopic limit rod 106 and the multi-stage hydraulic rod 105, and a rotating component 108 is embedded in the top seat 107. The top of the moving assembly 108 is connected to the workbench 2, so that the workbench 2 is rotatably connected to the top seat 107. During operation, the multi-stage hydraulic rod 105 can drive the top seat 107 to move up and down to adjust its height, and then the top seat 107 will move up and down together with the workbench 2, so as to adjust the height of the workbench 2. When laying cables, it can adapt to different scenes. Moreover, at the beginning, when personnel need to stand on the workbench 2, the workbench 2 can be adjusted to the lowest position to facilitate the entry of personnel. At this time, tools such as ladders or cranes can be used to send personnel to the workbench 2, and then it can be raised for operation;

[0034] When the multi-stage hydraulic rod 105 is working, the telescopic limit rods 106 on both sides thereof are extended or shortened together, which plays the role of limiting and improving stability. If the direction of the workbench 2 needs to be adjusted, the rotating assembly 108 is started, which can drive the workbench 2 to rotate horizontally on the top seat 107, thereby increasing its practicality.

[0035] In order to improve the stability of the base 1, a fixing sleeve 103 is provided on the bottom plate 101 on the outside of the telescopic limit rod 106. The fixing sleeve 103 is embedded in the bottom plate 101, and a fixing rod 104 is installed on the inner thread of the fixing sleeve 103. The bottom of the fixing rod 104 is a conical structure. After the position of the spanning frame is selected, the fixing rod 104 is rotated, and it can move down in the fixing sleeve 103 and insert into the ground, thereby improving the stability of the spanning frame. On the contrary, it is separated from the ground to realize the movement of the spanning frame.

[0036] The workbench 2 includes a protection frame 21, and a plurality of guardrails 22 are arranged in the peripheral side walls of the protection frame 21, which protect the personnel inside and improve the safety. In addition, a roller 23 is arranged in the middle position of the guardrails 22 on the front and rear side walls, and the roller 23 helps the personnel to place the cable. The cable is placed on the roller 23, which is more convenient when the cable is pulled, and can also provide support for the cable;

[0037] A limit block 24 is provided at the bottom of the protection frame 21, and the limit block 24 is placed in a limit groove 109 provided on the upper surface of the top seat 107, and the two are slidably connected, and the interaction between the two can improve the stability of the workbench 2 during rotation;

[0038] A reeling mechanism 3 is provided at the front side of the lower end of the workbench 2. The reeling mechanism 3 can protect the road surface when the cable is being installed to prevent the cable from falling and causing an impact. The reeling mechanism 3 can automatically reel in the protective net 304 and release it when in use. In addition, a fixing structure 4 is provided at the rear side of the lower end of the workbench 2. The fixing structure 4 can realize clamping and fixing of the protective net 304 when the cable is being installed. When the cable is being installed, crossing frames are respectively arranged on both sides of the road surface or elevated frame to be installed. The different sides of the two crossing frames correspond to each other, so that the reeling mechanism 3 and the fixing structure 4 can correspond to each other. After the protective net 304 is pulled out and arranged on the road surface, its moving end is fixed by the fixing structure 4, so that the protective net 304 can be quickly installed and arranged, and the operation is convenient.

[0039] Specifically, the fixing structure 4 includes a fixing plate 41, two fixing plates 41 are provided, and they are symmetrical at the bottom of the protection frame 21. The fixing plates 41 are provided with fixing holes 42, and the fixing holes 42 can be plugged with the insertion rods 3073 in the winding mechanism 3, thereby realizing the connection and fixation of the protection net 304;

[0040] The winding mechanism 3 includes two mounting plates 301, which are symmetrically arranged at the lower end of the protection frame 21. A reel 302 rotatably connected thereto is arranged inside the mounting plates 301, and a motor 303 is installed on the outer side of one of the mounting plates 301, and the output shaft of the motor 303 is connected to the reel 302. At the same time, a protective net 304 is wound around the reel 302. After the motor 303 is started, it drives the reel 302 to rotate, thereby realizing the winding of the protective net 304 thereon. Conversely, the motor 303 drives the reel 302 to rotate slowly in the reverse direction, and a person can gradually pull the protective net 304 to unfold it and place it on the upper side inside to achieve a protective effect.

[0041] A counterweight rod 305 is provided at the outer end of the protection net 304, and the counterweight rod 305 can facilitate the pulling and rolling of the protection net 304. Elastic components 307 are provided at both the left and right ends of the counterweight rod 305. The insertion rod 3073 in the elastic component 307 is connected with the fixing hole 42 to realize the convenient installation and disassembly by utilizing the elastic effect, and the use is convenient;

[0042] Mounting holes 306 having the same structure as the fixing holes 42 are arranged on the left and right side walls of the reel 302, which are also designed to fix the protection net 304. The counterweight rod 305 is installed in the mounting holes 306 through the elastic component 307 to prevent the protection net 304 from sliding off and spreading after it is folded.

[0043] The end of the counterweight rod 305 is provided with an inner groove 3051, a slide groove 3052 is provided at the lower side of the inner groove 3051, an elastic component 307 is slidably provided in the inner groove 3051, and the elastic component 307 includes a moving rod 3071, the moving rod 3071 is located in the inner groove 3051, an insert rod 3073 is provided at the outer end of the moving rod 3071, a spring 3072 is provided at the inner end thereof, and a lever 3074 is provided at the lower side of the moving rod 3071, and the lever 3074 is located in the slide groove 3052. When in use, the lever 3074 is pulled to drive the moving rod 3071 to move. The rod 3071 slides in the inner groove 3051 and compresses the spring 3072 at the same time, so that the insertion rod 3073 retracts into the inner groove 3051. At this time, the counterweight rod 305 can be installed with the mounting hole 306 or the fixing hole 42. After alignment, release the lever 3074. Under the action of the spring 3072, the insertion rod 3073 will be inserted into the mounting hole 306 or the fixing hole 42 to achieve snap-on fixation. If disassembly is required, just move the lever 3074 again. The operation is simple and convenient, and can achieve a good fixed installation of the protective net 304.

[0044] The spanning frame of the utility model can provide convenience for the installation of cables, can be reused, is easy to operate, and avoids the trouble of temporarily building the installation structure in the prior art. At the same time, the workbench 2 can adjust the height and angle under the action of the base 1, which increases the practicality and adaptability of the spanning frame.

[0045] Moreover, the rolling mechanism 3 interacts with the fixed structure 4 to enable the protective net 304 to be unfolded by the user and rolled up when not in use. The operation is simple and convenient, which improves the efficiency of laying out the protective net 304 and provides convenience for the entire operation process.
