Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a steel structure purlin installation and lifting device. Background Technique

[0002] The purlin, also known as purline and truss rod, is a horizontal roof beam perpendicular to the roof truss or rafter, used to support the rafters or roofing materials. The purlin is a laterally bent (usually doubly bent) member, generally designed as a single-span simply supported purlin. The commonly used purlins are of two types: solid web type and light steel truss type.

[0003] In the prior art, in the construction of steel structures, purlins are required to support the rafters or roofing materials. In the existing steel structure construction, the purlins need to be hoisted to a high place, and the hoisting of purlins is generally carried out by a hoisting machine. However, the existing hoisting machine is not only restricted by the terrain during hoisting, but also shakes when lifting the purlins, which is very unstable. Therefore, we propose a steel structure purlin installation and lifting device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art. In the construction of steel structures, purlins are required to support the rafters or roofing materials. In the existing steel structure construction, the purlins need to be hoisted to a high place, and the hoisting of purlins is generally carried out by a hoisting machine. However, the existing hoisting machine is not only restricted by the terrain during hoisting, but also shakes when lifting the purlins, which is very unstable.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A steel structure purlin installation and lifting device includes a purlin body. A concave fixed seat is clamped around the purlin body, and the length of the fixed seat is three meters. Symmetrically fixed on the back of the fixed seat are first screw rod sliders. A lifting plate is installed around the first screw rod sliders, and the height of the lifting plate is four meters. Symmetrically fixed near the center on the back of the lifting plate are second screw rod sliders. A lifting seat is installed around the second screw rod sliders, and the height of the lifting seat is two meters. A connecting plate is fixed at the bottom of the lifting seat. First electric push rods are fixed at the four corners of the bottom of the connecting plate. A base is fixed around the fixed end of the first electric push rod, and the height of the base is two meters.

[0007] As a preferred scheme of the utility model, a clamping plate is installed near the front of the inside of the fixed seat. Three second electric push rods are fixedly connected through the fixed seat at the front of the clamping plate, and the fixed ends of the second electric push rods are fixedly connected with the fixed seat.

[0008] The technical effect of adopting the above further solution is that the second electric push rod can effectively push the clamping plate, so as to clamp the purlin body through the clamping plate and the fixed seat, thus ensuring its stability during the lifting process.

[0009] As a preferred solution of the present utility model, first linear guide rails are symmetrically arranged on the front surface of the lifting plate and around the first screw rod slider, and the first screw rod slider is slidably connected with the first linear guide rails. A first screw rod is rotatably connected inside the first linear guide rails, and the first screw rod is rotatably connected with the first linear guide rails.

[0010] The technical effect of adopting the above further solution is that the first linear guide rails can effectively limit the first screw rod slider, enabling it to move linearly.

[0011] As a preferred solution of the present utility model, first protective boxes are symmetrically fixedly connected to the top of the lifting plate. First driving motors are fixedly connected inside the first protective boxes, and the output ends of the first driving motors penetrate through the lifting plate and are fixedly connected to the first screw rods inside the first linear guide rails.

[0012] As a preferred solution of the present utility model, second linear guide rails are symmetrically arranged on the front surface of the lifting seat and around the second screw rod slider, and the second screw rod slider is slidably connected with the second linear guide rails. Second screw rods are rotatably connected inside the second linear guide rails, and the second screw rods are rotatably connected with the second linear guide rails.

[0013] As a preferred solution of the present utility model, second protective boxes are fixedly connected to the top of the lifting seat. Second driving motors are fixedly connected inside the second protective boxes, and the output ends of the second driving motors penetrate through the lifting seat and are fixedly connected to the second screw rods inside the second linear guide rails.

[0014] The technical effect of adopting the above further solution is that the second driving motor can effectively provide power for the second screw rod.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] In the present utility model, through the provision of the fixing base, the fixing base can effectively limit the purlin body, and the purlin body can be clamped by the second electric push rod and the clamping plate, so that when the purlin body is lifted, it can be more stable and will not shake. The first screw slider can drive the fixing base to lift upward in the first linear guide rail, so that while ensuring stability, the purlin body can also be lifted to a certain height. By the second screw slider moving in the second linear guide rail, the fixing base can be further lifted to a certain height, and in cooperation with the first electric push rod, the purlin body can be lifted to the height of the roof, and at the same time, the stability of the lifting process can be ensured, thus making the installation process of the steel structure smoother and safer.

[0027] Embodiment 2

[0028] As Figures 1-3 shown, a clamping plate 21 is installed near the front of the inside of the fixed seat 2. Three second electric push rods 22 are fixedly connected through the front of the clamping plate 21 and equidistantly penetrate the fixed seat 2. The fixed end of the second electric push rod 22 is fixedly connected with the fixed seat 2. By the second electric push rod 22, the clamping plate 21 can be effectively pushed, so that the clamping plate 21 can cooperate with the fixed seat 2 to clamp the purlin body 1.

[0029] On the front of the lifting plate 4 and symmetrically around the first screw rod sliders 3, first linear guide rails 41 are provided. The first screw rod sliders 3 are slidably connected with the first linear guide rails 41. Inside the first linear guide rails 41, a first screw rod 42 is rotatably connected, and the first screw rod 42 is rotatably connected with the first linear guide rails 41.

[0030] The top of the lifting plate 4 is symmetrically fixedly connected with a first protective box 43. Inside the first protective box 43, a first driving motor 44 is fixedly connected. The output end of the first driving motor 44 penetrates through the lifting plate 4 and is fixedly connected with a first lead screw 42 inside the first linear guide 41. The first driving motor 44 can effectively drive the first lead screw 42 to rotate.

[0031] On the front of the lifting seat 6 and symmetrically around the second lead screw slider 5, second linear guides 61 are provided.
