Abstract
Description
Technical Field
[0001] This utility model relates to the field of transport frame technology, specifically a transport frame for precast concrete components. Background Technology
[0002] A precast concrete component transport rack is a specialized piece of equipment designed for the safe transport of precast concrete components (such as precast beams, columns, wall panels, floor slabs, stairs, etc.). Its core function is to ensure the stability of precast components during transport through structural design and a fixing system, preventing damage or deformation caused by bumps, collisions, or other factors, while also optimizing transport efficiency and loading space.
[0003] Existing patent document CN211996569U discloses a concrete precast component transport frame, including a crossbeam. A sturdy rod is fixedly connected to one outer surface of the crossbeam near the middle position, and an anti-collision rod is provided at the upper end of the sturdy rod. A vertical pole is fixedly connected to the front outer surface of the crossbeam, and a support rod is threadedly connected to one outer surface of the vertical pole near the middle position. A connecting rod is fixedly connected between adjacent sets of vertical poles. A ladder is fixedly welded to the other outer surface of the crossbeam near the middle position. This utility model can fix the transported materials on the transport frame, effectively protect the transported materials, reduce the risk of damage during transportation, avoid cracking and breakage caused by collisions between materials, facilitate user movement, and be easily disassembled when not in use for easy storage. This equipment is simple, easy to operate, and more effectively solves the problem of damage during transportation.
[0004] However, existing precast concrete component transport frames have poor adaptability due to varying transport volumes and the difficulty in adjusting the width between frames to hold and secure the precast concrete components during transport. Furthermore, the transport frames are often placed directly on the transport vehicle, and due to inertia, they may slip, leading to instability. Therefore, we propose a new precast concrete component transport frame. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a concrete precast component transport frame to solve the problems mentioned in the background section.

[0013] Preferably, a sliding block is bolted to the bottom of the sliding frame, and the sliding block is bolted to the nut seat.
[0014] (III) Beneficial Effects
[0015] This utility model provides a transport frame for precast concrete components, which has the following advantages:
[0016] (1) This type of precast concrete component transport frame, through the setting of the retracting rod and clamping plate, when the precast concrete component transport frame is placed on the transport vehicle, when there are no truck bed plates on both sides of the transport vehicle, the workers place the clamping plate on both sides of the truck bed, and then rotate the adjusting worm gear clockwise through the retracting handwheel. The adjusting worm gear drives the clockwise and counterclockwise screw to rotate through the worm wheel. The retracting rod can move inward due to the rotation direction of the clockwise and counterclockwise screw, and the retracting rod enters into the adjusting rod. At the same time, the clamping plate can clamp the two sides of the truck bed. When there are truck bed plates on both sides of the transport vehicle, the adjusting worm gear is rotated counterclockwise through the retracting handwheel. The retracting rod can move outward due to the rotation direction of the clockwise and counterclockwise screw, and the retracting rod moves out of the adjusting rod. At the same time, the clamping plate can push the truck bed plate outward, so that the precast concrete component transport frame can be installed according to the needs, and the transport frame will not slide due to inertia during transportation, thus improving the stability of the transport frame placement.
[0017] (2) This type of concrete precast component transport frame, through the set transport base, adjusting screw, nut seat and sliding frame, when the transport frame is placed, the workers place the concrete precast component on the transport base. After placement, the workers drive the adjusting screw to rotate by adjusting the handwheel. The nut seat, due to the rotation direction of the adjusting screw, drives the sliding frame to slide along the sliding groove through the sliding block. At the same time, the telescopic screw enters into the storage rod, causing the sliding frame to move closer to the support frame and clamp and fix the concrete precast component. This allows the transport frame to be adjusted according to the amount of concrete precast component placed, thus improving the adaptability of the transport frame. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a concrete precast component transport frame, including a transport base 1, an adjusting screw 2 movably connected through one side of the transport base 1, an adjusting handwheel 3 fixedly connected to one end of the adjusting screw 2, a nut seat 201 threadedly connected to the outer side of the adjusting screw 2, adjusting rods 5 welded to both the front and back of the transport base 1, retracting rods 8 slidably connected through both sides of the adjusting rods 5, a clamping plate 9 rotatably connected to one end of the retracting rods 8, a mounting bearing 15 installed inside the adjusting rods 5, a forward and reverse screw 16 installed inside the adjusting rods 5 through the mounting bearing 15, a support frame 10 bolted to one side of the top of the transport base 1, sliding grooves 501 opened on the top of both the transport base 1 and the adjusting rods 5, and a sliding frame 11 slidably connected to the top of the transport base 1 and the adjusting rods 5 through the sliding grooves 501.
[0025] Furthermore, the front and back of the adjusting rod 5 are both penetrated by adjusting worm gears 6. One end of the adjusting worm gear 6 is fixedly connected to a retractable handwheel 7. By rotating the retractable handwheel 7, the adjusting worm gear 6 can be driven to rotate. At the same time, the adjusting worm gear 6 drives the clockwise and counterclockwise screws 16 to rotate through the worm wheel 17.
[0026] Furthermore, a support rod 4 is welded to the inner side of the transport base 1. There are six support rods 4 arranged at equal intervals, which can provide support.
[0027] Furthermore, a worm gear 17 is keyed to the outer side of the forward and reverse screw 16. The worm gear 17 is meshed with the adjusting worm 6. The forward and reverse screw 16 is threadedly connected to the take-up and release rod 8. By rotating the adjusting worm 6 through the take-up and release handwheel 7, the adjusting worm 6 drives the forward and reverse screw 16 to rotate through the worm gear 17. The take-up and release rod 8 can then move inward due to the rotation direction of the forward and reverse screw 16.
[0028] Furthermore, both the support frame 10 and the sliding frame 11 have a screw hole 12 on one side. The support frame 10 and the sliding frame 11 are connected by a telescopic screw 13 through the screw hole 12. The outer side of the telescopic screw 13 is movably connected to a storage rod 14. When the nut seat 201 adjusts the rotation direction of the screw 2, the sliding frame 11 is driven to slide along the sliding groove 501 through the sliding block 1101, and at the same time, the telescopic screw 13 enters into the storage rod 14.
[0029] Furthermore, a sliding block 1101 is bolted to the bottom of the sliding frame 11. The sliding block 1101 is bolted to the nut seat 201, so that the nut seat 201 can drive the sliding frame 11 to move through the sliding block 1101 when it moves.
[0030] Working Principle: After installation, first check the installation, fixation, and safety protection of this utility model. When placing the precast concrete component transport frame on the transport vehicle, if there are no side decks on either side of the transport vehicle, the worker places the clamping plate 9 on both sides of the side deck. Then, the worker rotates the adjusting worm gear 6 clockwise via the retraction / release handwheel 7. The adjusting worm gear 6 drives the clockwise / counterclockwise screw 16 to rotate via the worm wheel 17. The retraction / release rod 8 moves inward due to the rotation direction of the clockwise / counterclockwise screw 16, entering the adjusting rod 5. Simultaneously, the clamping plate 9 clamps the sides of the side deck. When there are side decks on both sides of the transport vehicle, the worker rotates the adjusting worm gear 6 counterclockwise via the retraction / release handwheel 7. The retraction / release rod 8 moves inward due to the rotation direction of the clockwise / counterclockwise screw 16, entering the adjusting rod 5. At the same time, the clamping plate 9 clamps the sides of the side deck. The rotation direction of 6 allows it to move outwards, and at the same time, the retractable rod 8 moves out of the adjusting rod 5, and the clamping plate 9 can push against the truck bed plate outwards. When the transport frame is placed, the worker places the precast concrete component on the transport base 1. After placement, the worker drives the adjusting screw 2 to rotate by adjusting the handwheel 3. The nut seat 201, due to the rotation direction of the adjusting screw 2, drives the sliding frame 11 to slide along the sliding groove 501 through the sliding block 1101. At the same time, the telescopic screw 13 enters into the storage rod 14, causing the sliding frame 11 to move closer to the support frame 10 and clamp and fix the precast concrete component. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
