Description

Technical Field

[0001] This utility model belongs to the field of mobile crane technology, specifically relating to a mobile crane for the production of multi-layer composite flooring. Background Technology

[0002] Multi-layer composite flooring uses multi-layer plywood as the base material and hardwood veneer or sliced ​​veneer as the surface layer, which is then glued and hot-pressed together. Specifically, multi-layer solid wood composite flooring is also known as impregnated paper laminate veneer multi-layer solid wood composite flooring. Its process involves using impregnated paper laminate as the veneer layer and plywood as the base material, which are then pressed and processed together. It has the characteristics of wear resistance, deformation resistance, and high stability, and is currently a popular type of flooring on the market.

[0003] In the processing of multi-layer composite flooring, a hot press is used to press the multi-layer boards together. To improve processing efficiency, several groups of boards are usually processed simultaneously using a multi-layer hot press. This requires a mobile trolley that can load and unload the boards. The specific process is as follows: the boards needed for the composite flooring are laid out in sequence on the film-laying table, and then the laid-out boards are transferred one group at a time to the trolley that can carry multiple groups of boards. The trolley then transfers multiple groups of boards into the hot press plates of the multi-layer hot press for hot pressing and forming. After that, the trolley loads and transfers the hot-pressed boards to the film-laying table for further processing.

[0004] Currently, when mobile cranes are in use, their dimensions, floor height, and other parameters are usually matched with and remain unchanged by the hot press. However, they cannot be adapted to situations where composite flooring of various sizes and specifications needs to be processed, which causes great inconvenience, increases equipment investment, and makes them unsuitable for various working conditions.

[0045] The support member 23 is vertically installed on the fixed bracket along the horizontal direction, with one end connected to the fixed bracket, and several equally spaced gaps are formed between any two adjacent support members 23.

[0046] In some alternative embodiments, the support member may be a cylindrical long rod to prevent scratches on the surface of the plate during the pulling and pushing process.

[0047] In some alternative embodiments, the length of the support member is adjustable, specifically by adopting a telescopic rod structure, in which the length is adjusted by sliding multiple nested rod sections.

[0048] In some alternative embodiments, the length of the support member is adjustable. The support member consists of several segmented rods, with multiple sets of holes between two connected rods. The length is adjusted and fixed by inserting pins and bolts. The pins and bolts are located on the lower surface or side of the rods that do not contact the plate.

[0049] The end of the support member 23 connected to the fixed bracket is defined as the rear end, and the end of the support member 23 away from the fixed bracket is defined as the front end.

[0050] The support frame is slidably mounted on the base 1, and the sliding direction of the support frame is perpendicular to the extension direction of the support member 23.

[0051] Specifically, the mobile crane also includes guide rails. At least one set of guide rails is symmetrically arranged on the base 1 to prevent the support member 23 from being too long. Multiple sets of guide rails are evenly and parallelly distributed on the base to ensure the stability of the support frame.

[0057] In some optional embodiments, a limit sensing device is provided at the front end of the support member. When the edge of the plate completely enters the interlayer of the support member, an alarm or prompt can be made by displaying an indicator light or emitting an audible signal. The device can sense the position and transfer condition of the plate, including the distance between the edge of the plate and the front end of the support member, so as to determine the transfer condition of the plate.

[0058] The limit sensing device can be an ultrasonic rangefinder, specifically the HC-SR04 model; the limit sensing device can also be an infrared laser rangefinder, specifically the GLM80 model.

[0059] When the limit sensing device detects that the distance between the edge of the plate and the front edge of the support reaches the preset value, it will emit a beep or light to indicate that the corresponding step has been completed and the next step can be carried out.

[0060] See attached document Figure 3As shown, in the support part 2, several adjusting members 21 are spaced apart on the fixed bracket. The adjusting members 21 are correspondingly connected to the support part 23. One end of the connecting rod 22 is fixedly connected to the adjusting member 21, and the other end of the connecting rod 22 is movably connected to the adjusting member 21 located above and on another fixed bracket. The two connecting rods 22 are arranged in a cross pattern, and multiple sets of vertically oriented cross-shaped connecting rods are provided at the rear end of the support part 2.

[0061] The number of adjusting members 21 is the same as the number of supporting members 23. The adjusting member 21 located at the bottom is fixed in position, while the remaining adjusting members 21 can move up or down along the fixed bracket under the action of the connecting rod 22, thereby driving the corresponding supporting member 23 to move in position, and thus realizing the simultaneous adjustment of the spacing of the supporting members 23.

[0062] In some alternative embodiments, the adjusting member 21 and the connecting rod 22 are connected by fasteners, specifically by a pin installed at the connection between the adjusting member 21 and the connecting rod 22 to form a hinge.

[0063] In some alternative embodiments, the contact portions between the two intersecting links 22 are connected by fasteners. Specifically, a pin may be installed at the intersection of the two links 22, so that the two links 22 can rotate around the intersection, thereby driving the support connected to the adjusting member 21 to rise or fall and adjust its height.

[0064] The movable part 3 is disposed in the gap area between the two support frames. The movable part 3 is slidably disposed on the base 1, and the sliding direction of the movable part 3 is parallel to the extension direction of the support member 23.

[0065] Specifically, the mobile trolley also includes a slide rail, which is set on the base 1 and extends in a direction parallel to the extension direction of the support member 23. The moving part 3 is installed on the slide rail through a sliding structure set at the bottom and moves back and forth in a straight line along the slide rail towards the front and rear ends of the support member 23.

[0066] The slide rail adopts a T-slot or dovetail groove, and the bottom of the moving part 3 is provided with a slider with a fitting groove.

[0068] The end of the movable part 3 near the front end of the support member 23 is the front end of the movable part. Several guide hooks 5 are symmetrically arranged on the opposite sides of the front end of the movable part. The guide hooks 5 are arranged corresponding to the support member 23, and their extension direction is parallel to the extension direction of the support member 23.

[0072] Preferably, the angle adjustment range is 45°-165°.

[0073] More preferably, the angle adjustment range is 75°-105°.

[0074] The angle of the positioning part 52 relative to the horizontal direction (i.e. the extension direction of the extension part 51) can be adjusted according to the actual situation. It can usually be kept at a 90° vertical state during use. It can be adjusted according to the placement angle of the transport base plate, the positioning hole diameter and other factors, so that the guide hook 5 can more easily pass through the positioning hole to fix the plate.

[0075] The number of guide hooks 5 is at least equal to the number of support members 23. Each support member 23 corresponds to an adjacent guide hook 5. The support member 23 is positioned corresponding to the extension part 51. The upper surface of each corresponding support member 23 is flush with the upper surface of the extension part 51.

[0076] In some alternative embodiments, the front end of the movable part 3 may be provided with a plurality of guide hooks 5, wherein the extension part 51 is fixed to the front end face of the movable part 3, and the distance is adjusted by adjusting the installation position of the positioning part 52 on the extension part 51.

Several equally spaced gaps are formed between any two adjacent secondary support members 41 and they are close to the support frame.

[0082] In some alternative embodiments, the secondary support 41 may be a cylindrical long rod to prevent scratches on the surface of the plate during the pulling and pushing process.

[0083] The secondary support 4 also includes adjusting members and connecting rods.

[0096] The mobile crane also includes bottom wheels, which are located on the underside of the base 1 for crane movement.

[0097] The working principle of the mobile crane for producing multi-layer composite flooring provided by this utility model is as follows:

[0098] The sheets to be transported are placed on the laying platform. The layer spacing of the laying platform is adjusted according to the layer spacing between the multiple hot-pressed sheets of the hot press. The lifting device is adjusted to adjust the height of the overhead crane to match the laying platform. The layer spacing of the support part 2 is also adjusted to be equal to the layer spacing of the laying platform. The layer spacing of the secondary support part 4 is also adjusted accordingly to keep the upper surfaces of the corresponding secondary support parts 41 and support parts 23 at the same height. The height and vertical spacing of the guide hooks 5 are adjusted according to the layer spacing of the support parts 23. The distance between the support frames and the distance between the secondary support frames are adjusted according to the size of the sheets to ensure that the distance between the symmetrically arranged secondary support frames and secondary brackets is greater than the size of the sheet material entering the gap of the secondary support parts 41, ensuring that the sheets can be transported onto the overhead crane intact.

[0099] A base plate is laid under the plate. A guide hole is provided on the side of the base plate near the moving trolley. The trolley height is slightly lowered, the power device is started, and the front end of the moving part 3 is moved forward to the limit position. The guide hook 5 is controlled to move closer to the guide hole, and the trolley height is controlled to rise in time, so that the positioning part 52 passes through the guide hole of the base plate from bottom to top. The moving part 3 moves along the slide rail to the rear end of the support member 23. The plate passes through the gap at the front end of the support member 23 until the plate is completely placed on the support member 23 and the auxiliary support member 41.

[0100] The trolley moves to the limit position in front of the hot press and the height of the trolley is adjusted to match the height of the hot press. At this time, the front end of the moving part 3 is close to the rear end of the support member 23 and the front end of the support member 23 is close to the hot press. The moving part 3 moves along the slide rail to the front end of the support member 23. The plate enters the gap between the hot press plates of the hot press through the gap at the front end of the support member 23 until the plate, except for the area where the bottom plate guide hole is located, is completely placed on the hot press plate.

[0101] The crane height is slightly lowered, causing the positioning part 52 to leave the bottom plate guide hole from below. The moving part 3 is then controlled to move the crane backward, leaving the limit position. The hot press is then turned on to begin processing the sheet metal.

[0102] After the hot press is completed, the multi-layer composite board is placed on the base plate. The trolley moves to the limit position in front of the hot press and the height of the trolley is adjusted to match the height of the hot press. The trolley height is slightly lowered, the power unit is started, and the front end of the moving part 3 is moved forward. The guide hook 5 is controlled to move closer to the guide hole of the base plate, and the height of the trolley is raised in time, so that the positioning part 52 passes through the guide hole of the base plate from bottom to top. The moving part 3 moves along the slide rail to the rear end of the support member 23, and the board passes through the gap at the front end of the support member 23 until the board is completely placed on the support member 23 and the auxiliary support member 41.

[0103] The processed composite panels are then transferred to the transport device as described above to complete the unloading process.
