Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a precast beam turnover and transportation device with a clamping structure. Background Technology

[0002] Precast beams are beams that are prefabricated in a factory and then transported to the construction site for installation and fixation according to the design requirements. They are widely used in building and transportation engineering. The most common shape of precast beams is T-shaped. Precast beams require turnover devices during turnover and transportation, and turnover devices usually refer to turnover bases. However, existing turnover devices still have certain defects in use.

[0003] In existing technologies, precast beam turnover devices are usually placed on turnover carts. When using traditional turnover devices, the precast beams are first placed on the turnover device using hoisting equipment, and then the diagonal braces on the turnover device are used to fix the precast beams. This fixing method is not strong enough, and the bottom of the precast beams is usually placed directly on the turnover device, which is not stable enough. When the turnover device transports the precast beams by turnover cart, the precast beams are prone to uneven force distribution due to ground conditions, making them prone to twisting and overturning, and posing a risk of falling. This makes the turnover and transportation of precast beams quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a precast beam turnover and transportation device with a clamping structure to solve the problem mentioned in the background art that current turnover devices on the market are not easy to stably limit the position of precast beams.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A precast beam turnover and transportation device with a clamping structure includes a base with rollers. The clamping structure is located on the base and includes wedge-shaped clamping fast assemblies symmetrically arranged on the left and right sides of the base. Each wedge-shaped clamping fast assembly includes a knob handle, a knob rod, a lead screw, and a wedge block arranged sequentially. The lower part of the wedge block is confined within a groove in the base, and the lower part of the wedge block is threadedly connected to the lead screw. The upper part extends out of the groove to form the clamping part. Bearings are provided on both side walls inside the groove. The lead screw is fixed to the inner ring of the bearing, and the outer ring of the bearing is fixed to the inside of the groove. The end of the lead screw passing through the inner ring is fixed to the knob rod. The two wedge blocks approach each other to clamp the precast beam.

[0006] More preferably, it also includes inclined support members on the left and right sides of the support structure on the base. The inclined support member includes a connecting block, an inclined support rod, and a hinged top support. The connecting block is fixed on the base and has a limiting groove at the top. A bolt top rod is threadedly connected to the groove wall of the limiting groove. The bottom of the inclined support member rod is hinged to the bottom of the limiting groove, and the end of the bolt top rod abuts against the groove wall of the inclined support member.

[0007] Furthermore, the diagonal support is an adjustable-length diagonal strut.

[0008] Furthermore, the inclined support is an electro-hydraulic rod.

[0009] Furthermore, the hinged top support includes a rotating block, an L-shaped connecting rod, and a top plate, on which a rubber anti-slip pad is affixed.

[0010] Furthermore, the rotating block is confined within the groove on the top surface of the inclined support rod, the top plate is hinged to the horizontal part of the L-shaped connecting rod, and the vertical part of the L-shaped connecting rod is fixed to the top surface of the rotating block.

[0011] Furthermore, the upper part of the groove is also provided with a bellows telescopic protective cover.

[0012] In addition, the knob handle is equipped with a brake lever to prevent the knob handle from rotating.

[0013] More preferably, it also includes an additional support base that can be detachably fixed to the front and rear end faces of the base. The additional support base includes a main support plate and U-shaped connecting blocks on both sides of the main support plate. A positioning block is hinged to the U-shaped connecting block. The positioning block and the fixing block on the base are stacked and bolted together.

[0014] Compared with the prior art, this utility model has the following features and beneficial effects: Precast beam turnover devices are common in the construction and transportation industries. Traditional turnover devices are not easy to stabilize and limit the position of precast beams, making them prone to eccentric stress and twisting / overturning, resulting in inconvenience in the turnover and transportation of precast beams. In this application, when the knob handle is turned, it can drive the lead screw to rotate. When the two sets of lead screws rotate, they can drive the corresponding wedge blocks to slide closer to each other. When the wedge blocks move, the bellows telescopic protective covers on both sides can be compressed and expanded. When one side of both sets of wedge blocks moves to the two sides of the precast beam, the two sets of wedge blocks can clamp and limit the two sides of the precast beam. The inclined support can assist in the positioning of the upper part of the precast beam. Through the two sets of inclined support and the two sets of wedge blocks, the precast beam can be positioned and limited, making it less likely for the precast beam to twist and overturn due to uneven eccentric stress during turnover and transportation.

Detailed Implementation

[0017] To make the technical means, innovative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0018] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0019] Example 1 A precast beam turnover and transportation device with a clamping structure, such as Figures 1-4 As shown, the structure includes a base 1 with rollers, and a clamping structure 2 is provided on the base 1. The structure includes wedge-shaped clamping fast assemblies symmetrically arranged on the left and right sides of the base 1. The wedge-shaped clamping fast assemblies include a knob handle 21, a knob rod 22, a lead screw 23, and a wedge block 24 arranged in sequence. The lower part of the wedge block 24 is limited to a groove 25 provided in the base 1. The lower part of the wedge block 24 is threadedly connected to the lead screw 23. The width of the wedge block 24 gradually narrows from top to bottom, and the upper part extends out of the groove 25 to form a clamping part. Bearings 26 are provided on both sides of the inner wall of the groove 25. The two ends of the lead screw 23 are fixed to the inner ring of the bearing 26, and the outer ring of the bearing 26 is fixed to the inside of the groove 25. The end of the lead screw 23 that passes through the inner ring is fixed to the knob rod 22. The two wedge blocks 24 move close to each other to clamp the precast beam.

[0020] It also includes inclined support members 3 on the left and right sides of the support structure 2 on the base. The inclined support member 3 includes a connecting block 31, an inclined support rod 32 and a hinged top support 33. The connecting block 31 is fixed on the base 1 and has a limiting groove 34 at the top. A bolt top rod 35 is threadedly connected to the groove wall of the limiting groove 34. The bottom of the rod of the inclined support member 3 is hinged to the bottom of the limiting groove 34. The end of the bolt top rod 35 abuts against the rod wall of the inclined support member 3. The inclined support member 3 is an adjustable length inclined support rod, or an electric hydraulic rod can be selected. The hinged top support 33 includes a rotating block, an L-shaped connecting rod and a top plate. A rubber anti-slip pad is laid on the top plate.

[0021] The rotating block is confined within the groove on the top surface of the inclined support rod 32. The top plate is hinged to the horizontal part of the L-shaped connecting rod, and the vertical part of the L-shaped connecting rod is fixed to the top surface of the rotating block. The groove 25 is also equipped with an accordion telescopic protective cover 27. The knob handle 21 is equipped with a brake rod to prevent the knob handle 21 from rotating. The accordion telescopic protective covers on both sides can be compressed and expanded. The accordion telescopic protective covers can reduce the contamination of the lead screw by external dust.

[0022] Example 2 Based on Embodiment 1, it also includes an additional support base 4 that is detachably fixed to the front and rear end faces of the base 1. The additional support base 4 includes a main support plate 41 and U-shaped connecting blocks 42 disposed on both sides of the main support plate 41. A positioning block 43 is hinged to the U-shaped connecting block 42. The positioning block 43 and the fixing block 44 disposed on the base 1 are stacked and bolted together.

[0023] In practice, when using the precast beam turnover device, the contact area between the bottom of the precast beam and the top surface of the turnover base is small, resulting in low stability of the precast beam placement. Before placing the precast beam, the two sets of additional support seats can be pushed towards the front and rear of the turnover base respectively. The bolts inside the fixing block can be tightened. When the bolts are tightened, the bolt part can slide into the positioning block, thereby fixing the positioning block. This allows the additional support seats to be installed at the front and rear of the turnover base. The top surface of the additional support seat 4 is at the same height as the turnover base.

[0024] The anti-slip texture on the surface of the additional support 4 can increase the frictional resistance with the bottom of the precast beam, making the precast beam less prone to slipping. At the same time, the additional support 4 can increase the contact area with the bottom of the precast beam, thereby improving the stability of the precast beam placement.

[0025] In summary, when using this adjustable, reusable device to prevent precast beams from twisting and overturning due to eccentric force, the two sets of knobs can be rotated clockwise. Rotating the knobs causes the lead screws to rotate, and rotating the lead screws causes the corresponding wedge blocks to slide closer together. When both sets of diagonal braces are fixed, the precast beams can be positioned in a limited manner using the two sets of diagonal braces and the two sets of wedge blocks. This prevents the precast beams from twisting and overturning due to uneven eccentric force during transport, thus improving the stability of the precast beam placement. Any content not described in detail in this specification is prior art known to those skilled in the art.
