Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipe production, in particular to a transfer vehicle for thermal insulation pipe production. Background Art

[0002] PP-R polyurethane insulated pipe is closely combined with PP-R working pipe, polyurethane rigid foam insulation layer and PE high-density polyethylene outer protective layer to form a "three-in-one" structure, which realizes the functions of pipeline anti-corrosion, insulation and force transmission. With the development of material technology, the application of PP-R polyurethane insulated pipe is constantly expanding, and it is now widely used in municipal, building water supply and drainage, gas transmission and distribution and other fields. The application of heat-resistant plastic materials has enabled the application of plastic pipes to develop from the field of normal temperature transportation to the field of hot water transportation, providing a new choice for pipe materials for heating pipe networks.

[0003] During the production process of PP-R polyurethane insulated pipes, the PP-R polyurethane insulated pipes need to be transferred from the production workshop to the storage warehouse or from the storage warehouse to the warehouse through a cart for auxiliary transfer. In order to prevent the insulation pipes from rolling and deviating, traditional PP-R polyurethane insulated pipe transfer carts will fix and weld multiple columns on the top of the cart bottom plate to limit the stacked insulation pipes on both sides. However, such a structure also restricts the taking and placing of the insulation pipes from both sides of the cart. The insulation pipes themselves are relatively long. When the insulation pipes are taken and placed from both ends of the cart, the friction between the insulation pipes is relatively large. Based on this, a transfer cart for insulation pipe production is provided. Utility Model Content

[0028] The limiting assembly 2 includes a C-shaped fixed column 201, a middle C-shaped column 202, and a top C-shaped column 203;

[0029] The C-shaped fixed column 201, the middle C-shaped column 202, and the top C-shaped column 203 are distributed from bottom to top and the outer wall sizes are increased in sequence. The C-shaped fixed column 201 is fixed to the top of the mobile body 1;

[0030] A locking connection assembly 3 is provided between the C-shaped fixed column 201 and the middle C-shaped column 202, and between the middle C-shaped column 202 and the top C-shaped column 203. The locking connection assembly 3 is used to realize the folding and storage of the top C-shaped column 203 and the middle C-shaped column 202, and the folding and storage of the middle C-shaped column 202 and the C-shaped fixed column 201. The height of the limiting assembly 2 is reduced by folding and storing the top C-shaped column 203 and the middle C-shaped column 202, so as to realize convenient taking and placing of the insulation pipe from the side of the mobile body 1;

[0031] The locking connection assembly 3 includes a fixing seat 301, a fixing shaft 302, a locking hole 303, a horizontal rod 305, and a locking column 306;

[0032] The fixing seat 301 is symmetrically fixed to the top of the C-shaped fixing column 201 and the middle C-shaped column 202, the fixing shaft 302 is fixed in the middle of the two fixing seats 301, and the bottom of the middle C-shaped column 202 and the bottom of the top C-shaped column 203 are rotatably connected to the fixing shaft 302;

[0033] The locking hole 303 is formed inside the fixed shaft 302 and passes through the upper and lower ends of the fixed shaft 302;

[0034] The horizontal rod 305 is vertically slidably connected to the middle C-shaped column 202 and the top C-shaped column 203, and the locking column 306 is fixed to the bottom of the horizontal rod 305 and clamped to the inner side of the locking hole 303, so as to realize the locking of the middle C-shaped column 202 and the top C-shaped column 203 in the vertical state;

[0035] The locking connection assembly 3 also includes a vertical slide groove 304, a spring 307, and a fixing block 308;

[0036] The vertical slide groove 304 is provided at the position where the middle C-shaped column 202 and the top C-shaped column 203 contact the horizontal rod 305. The horizontal rod 305 is slidably connected to the vertical slide groove 304. The horizontal rod 305 moves upward along the track of the vertical slide groove 304 to drive the locking column 306 to separate from the locking hole 303, so as to realize the unlocking of the middle C-shaped column 202 and the top C-shaped column 203 in the vertical state.

[0037] The fixing block 308 is fixed to the inner side of the middle C-shaped column 202 and the top C-shaped column 203 and is located above the horizontal rod 305. The spring 307 is fixedly connected between the horizontal rod 305 and the fixing block 308. The spring 307 in the contracted state is used to provide a restoring force for the horizontal rod 305.

[0038] A J-shaped slot 204 is provided at a position near the top of one side of the outer wall of the C-shaped fixed column 201 and the middle C-shaped column 202. When the top C-shaped column 203 and the middle C-shaped column 202 are folded and stored, the J-shaped slot 204 is used for storing and locking the horizontal rod 305;

[0039] An arc-shaped receiving groove 205 is provided near the bottom of one side of the outer wall of the C-shaped fixed column 201. When the top C-shaped column 203 and the middle C-shaped column 202 are folded in sequence, the arc-shaped receiving groove 205 is used to receive the horizontal rod 305 on the top C-shaped column 203.

[0040] In this embodiment: when the transfer vehicle is in daily use, the insulation pipes are stacked in sequence and placed on the top of the mobile vehicle body 1, and the limit assemblies 2 on both sides thereof form limits with the two sides of the insulation pipes, and the stacking height of the insulation pipes is not higher than the top horizontal height of the top C-shaped column 203, so as to ensure that the insulation pipes will not deviate and fall during the movement and transfer of the mobile vehicle body 1;

[0041] When it is necessary to take the insulation pipes, the insulation pipes distributed on the upper layer can be taken from both sides of the mobile body 1. After taking a part of the insulation pipes, when the height of the stacked insulation pipes is close to the top height of the middle C-shaped column 202, the top C-shaped column 203 can be folded. The operation steps are as follows:

[0042] The horizontal rod 305 slidably connected to the top C-shaped column 203 is pulled upward, and the horizontal rod 305 drives the locking column 306 to move upward and squeeze the spring 307 to contract, so that the locking column 306 is separated from the locking hole 303. At this time, the lock of the top C-shaped column 203 is released, and then the top C-shaped column 203 is rotated, and the top C-shaped column 203 is rotated downward with the fixed axis 302 as the center and stored inside the middle C-shaped column 202;

[0043] During this process, the horizontal rod 305 rotates synchronously and enters the J-shaped slot 204. At this time, the pulling on the horizontal rod 305 is released. At this time, under the action of the restoring elastic force of the spring 307, the horizontal rod 305 is reset and moves upward, and the horizontal rod 305 is stuck in the top groove of the J-shaped slot 204, so that the horizontal rod 305 and the middle C-shaped column 202 are locked;

[0044] After that, the insulation pipes can be taken out. When the stacking height of the insulation pipes is close to the top height of the C-shaped fixed column 201, the middle C-shaped column 202 can be folded. The operation steps are the same as the folding operation of the top C-shaped column 203. The middle C-shaped column 202 and the top C-shaped column 203 are rotated and stored inside the C-shaped fixed column 201. The two horizontal rods 305 are respectively stuck in the J-shaped slot 204 and the arc-shaped storage slot 205 on the C-shaped fixed column 201.

[0045] After the middle C-shaped column 202 is folded, the insulation tubes can be taken out continuously until all the insulation tubes are taken out. When the insulation tubes are placed, the operation steps are opposite to the above steps. When the insulation tubes are stacked to a height close to the top of the C-shaped fixed column 201, the middle C-shaped column 202 is unfolded. When the insulation tubes are stacked to a height close to the middle C-shaped column 202, the bottom C-shaped column is unfolded.

[0046] The top C-shaped column 203 and the middle C-shaped column 202 can be conveniently folded and unfolded by cooperating with the above-mentioned multiple parts, thereby realizing the adjustment of the height of the limit assembly 2. Compared with the traditional structure with constant height, the insulation pipe can be better taken and placed from the side of the mobile body, and the overall operation is simple and convenient.

[0047] Please refer to Figures 1-2 Each set of limiting components 2 includes multiple sets of C-shaped fixed columns 201, middle C-shaped columns 202, and top C-shaped columns 203, and the horizontal rod 305 passes through the multiple sets of middle C-shaped columns 202 and top C-shaped columns 203.

[0048] In this embodiment: this structure can realize the synchronous folding and unfolding operations of multiple sets of middle C-shaped columns 202 and top C-shaped columns 203.

[0049] Please refer to Figures 1 to 3 When the middle C-shaped column 202 and the top C-shaped column 203 are in a vertical state, the side of the C-shaped fixed column 201, the middle C-shaped column 202, and the top C-shaped column 203 away from the opening are aligned, and the J-shaped slot 204 and the arc-shaped storage slot 205 are opened on the opening side of the C-shaped fixed column 201 and the middle C-shaped column 202.

[0050] In this embodiment: the side of the C-shaped fixed column 201, the middle C-shaped column 202, and the top C-shaped column 203 away from the opening is in contact with the insulation pipe. The flush state of this side can avoid scratches on the insulation pipe.

[0051] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
