Description

Technical Field

[0001] The invention relates to the technical field of threaded steel processing, and in particular to a limiting device for a threaded steel fixed-length collection rack. Background Art

[0002] Rebar is the common name for hot-rolled ribbed steel bars, and a rebar fixed-length collection rack is a device used to store and manage rebar materials, especially in construction sites or material warehouses. This collection rack can help organize rebars of different lengths for easy access and reduced material loss. Collection racks are usually designed to accommodate rebars of a specific length so that they can be classified and stored according to the fixed length.

[0003] At present, the threaded steel collection rack in the workshop usually relies on manual threading of steel wire ropes and then uses a crane to lift the threaded steel. However, when the threaded steel collection rack is storing materials and the crane cannot lift the steel in time, the threaded steel collection rack cannot identify the stacking position, resulting in the inability to close the pushing cylinder in time, resulting in accumulation, and unable to leave enough safety distance. When subsequent employees enter the collection rack area to operate, there is a risk of being scalded or squeezed by hot materials, which poses certain safety hazards. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a limit device for a threaded steel fixed-length collection rack, which has the function of monitoring the collection and stacking position of the threaded steel, realizing the fixed-point closing of the pushing cylinder, and reserving a sufficient safety distance, thereby achieving the technical effect of safe production in the workshop.

[0005] In order to solve the above technical problems and achieve the above technical effects, the present invention is implemented through the following technical solutions: The technical solution of the present invention is: a limiting device for a threaded steel fixed-length collection rack, comprising a lever assembly arranged on the threaded steel collection rack and a sensing assembly arranged on the collection rack leg; the lever assembly comprises a rotating rod arranged on the threaded steel collection rack, the surface of the rotating rod is rotatably connected with a curved rod parallel to the height of the threaded steel collection rack, one end of the curved rod is provided with a connecting rope, the other end of the curved rod is provided with a parallel portion, and a heavy hammer assembly is provided at the bottom of the connecting rope; the sensing assembly comprises a lower support frame fixedly installed on the inner side of the collection rack leg, a proximity switch capable of sensing the position of the heavy hammer assembly is provided inside the lower support frame, and a wire is provided at one end of the proximity switch close to the collection rack leg, and the proximity switch and PCL are connected by the wire signal; an upper support frame is fixedly installed on the inner side of the collection rack leg, and a heavy hammer protection plate capable of limiting the position of the heavy hammer assembly is provided at one end of the upper support frame.

[0006] Furthermore, the weight assembly includes a connecting ring connected to the bottom end of the connecting rope, a connecting plate is fixedly installed on the bottom end of the connecting ring, an adjusting assembly is fixedly installed on the bottom end of the connecting plate, and a weight used in conjunction with the proximity switch is fixedly installed on the bottom of the adjusting assembly.

[0007] Furthermore, the adjustment assembly includes a threaded rod fixedly mounted on the bottom of the connecting plate, an extension tube is threadedly connected to the surface of the threaded rod, and the bottom of the extension tube is fixedly connected to the top of the weight.

[0008] Furthermore, a baffle capable of limiting the position of the threaded steel bundle is fixedly installed on the outer end of the threaded steel collection rack.

[0009] Furthermore, the baffle is arranged in an L-shape, and the top end of the baffle is higher than the height of the threaded steel collecting rack.

[0010] Furthermore, a concave groove adapted to the weight assembly is formed at the outer end of the weight protection plate, and a weight buffer pad capable of providing buffering is provided on the inner wall of the concave groove.

[0011] Furthermore, a connection hole adapted to the proximity switch is provided inside the lower support frame, and the proximity switch is fixedly connected to the lower support frame by bolts.

[0012] Furthermore, a wire harness assembly capable of assisting in limiting the position of the wires is disposed on the inner side of the collecting rack legs, and the wire harness assembly includes a plurality of wire harness clamps detachably connected to the collecting rack legs, and the plurality of wire harness clamps are spaced apart along the height direction of the collecting rack legs.

[0013] Furthermore, the cross-section of the cable tie is concave, and the cable tie is connected to the inner wall of the collecting frame leg by bolts.

[0014] Furthermore, a wire bundle tube capable of storing and guiding the wires is provided at the bottom of the threaded steel collection rack.

[0015] The beneficial technical effect of the present invention is that during the collection of fixed-length rebars, the pushing cylinder will push the rebars to be collected on the rebar collection rack for fixed-length collection. During this process, when the rebars move to the top of the side lever assembly on the rebar collection rack, the rebars will press one end of the lever assembly downward due to their own gravity, so that the other end of the lever assembly drives the weight assembly away from the sensing assembly. At this time, the proximity switch in the sensing assembly cannot detect the weight assembly, so it sends a command to the PLC to close the pushing cylinder through the wire, so that the rebar fixed-length collection rack can reserve a certain safety distance when collecting the rebars, which is convenient for subsequent staff to thread the wire rope, and solves the problem that the pushing cylinder cannot be closed in time during the stacking process, and sufficient safety distance cannot be left. When subsequent employees enter the collection rack area to operate, there is a risk of being scalded or squeezed by hot materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0019] See attached Figure 1-Figure 3 As shown, a limiting device for a threaded steel fixed-length collection rack includes a lever assembly arranged on the threaded steel collection rack 1 and a sensing assembly arranged on the collection rack support leg 14; the lever assembly includes a rotating rod 2 arranged on the threaded steel collection rack 1, and the surface of the rotating rod 2 is rotatably connected to a curved rod 3 which is highly parallel to the threaded steel collection rack 1, and the curved rod 3 rotates around the rotating rod 2 as the center.

[0020] A connecting rope 4 is provided at one end of the curved rod 3, and a parallel portion is provided at the other end of the curved rod 3. The parallel portion is higher than the height of the threaded steel collecting rack 1. A baffle 15 capable of limiting the threaded steel bundle is fixedly installed at the outer end of the threaded steel collecting rack 1. The baffle 15 is L-shaped, and the top of the baffle 15 is higher than the height of the threaded steel collecting rack 1. The baffle 15 can assist in limiting the threaded steel so that the threaded steel will not fall off the threaded steel collecting rack 1. At the same time, the distance between the baffle 15 and the curved rod 3 is convenient for the staff to observe whether the safety distance is met.

[0021] A weight assembly is provided at the bottom of the connecting rope 4, and the weight assembly includes a connecting ring 6 connected to the bottom end of the connecting rope 4, a connecting plate 5 is fixedly installed at the bottom end of the connecting ring 6, an adjusting assembly is fixedly installed at the bottom end of the connecting plate 5, and a weight 8 used in conjunction with the proximity switch 10 is fixedly installed at the bottom of the adjusting assembly.

[0022] Lever assembly not working state: under the influence of the gravity of the weight hammer 8, when the bent lever 3 is not in the triggered working state, the parallel part of the bent lever 3 is higher than the height of the threaded steel collecting frame 1 and the weight hammer assembly is within the recognition range of the sensing assembly; Working status of the lever assembly: when the rebar is pushed onto the parallel part of the bent rod 3, since the weight of the rebar is greater than the weight of the weight assembly, the parallel part of the bent rod 3 moves down to be consistent with the height of the rebar collection rack 1. At this time, the other end of the bent rod 3 pulls the weight assembly upward through the connecting rope 4. At this time, the weight assembly is not within the recognition range of the sensing assembly.

[0023] The sensing component includes a lower support frame 11 fixedly installed on the inner side of the collecting frame leg 14, and a proximity switch 10 capable of sensing the position of the heavy hammer assembly is arranged inside the lower support frame 11. A connecting hole adapted to the proximity switch 10 is opened inside the lower support frame 11, and the proximity switch 10 is fixedly connected to the lower support frame 11 by bolts, and a wire 18 is arranged at one end of the proximity switch 10 close to the collecting frame leg 14, and the proximity switch 10 and the PCL are connected by signal through the wire 18.

[0024] An upper support frame 12 is fixedly installed on the inner side of the collecting frame leg 14, and one end of the upper support frame 12 is provided with a heavy hammer protection plate 16 which can limit the heavy hammer assembly. The outer end of the heavy hammer protection plate 16 is provided with a concave groove adapted to the heavy hammer assembly, and the inner wall of the concave groove is provided with a heavy hammer buffer pad 17 which can be used to provide buffering. The heavy hammer protection plate 16 can limit the heavy hammer assembly when it approaches the proximity switch 10 to prevent the heavy hammer assembly from causing damage to the proximity switch 10, and when the heavy hammer assembly contacts the heavy hammer protection plate 16, the heavy hammer buffer pad 17 on the inner wall of the heavy hammer protection plate 16 can provide cache protection, thereby increasing the service life of the heavy hammer protection plate 16 and reducing noise.

[0025] When the other end of the curved rod 3 pulls the heavy hammer assembly upward through the connecting rope 4, the proximity switch 10 disconnects the detection of the heavy hammer 8 in the heavy hammer assembly, so that the proximity switch 10 sends a command to the PLC through the wire 18, so that the PLC controls and closes the pushing cylinder, thereby leaving a sufficient safety distance. This avoids the situation in which the pushing cylinder is not closed in time during the stacking process, resulting in a failure to leave a sufficient safety distance. When subsequent employees enter the collection rack area to operate, there is a risk of being scalded or squeezed by hot materials, which makes it easier for subsequent staff to thread the wire rope.

[0026] Furthermore, the adjustment component includes a threaded rod 9 fixedly mounted on the bottom of the connecting plate 5, and the surface of the threaded rod 9 is threadedly connected with an extension tube 7, and the bottom of the extension tube 7 is fixedly connected to the top of the weight 8. By setting the threaded connection between the threaded rod 9 and the extension tube 7, when it is necessary to adjust the height position of the weight 8 to match the position of the proximity switch 10, after the lever assembly is installed, the extension tube 7 can be rotated so that the extension tube 7 can be expanded and extended through the thread on the threaded rod 9, and the position of the weight 8 can be fine-tuned to make it better adapt to the position of the proximity switch 10, thereby avoiding the problem of the proximity switch 10 sensing error caused by being too high or too low.

[0027] See attached Figure 2-Figure 4 As shown, a wire harness tube 19 capable of storing and guiding the wires 18 is disposed at the bottom of the threaded steel collection rack 1, and a wire harness assembly capable of assisting in limiting the wires 18 is disposed on the inner side of the collection rack leg 14, and the wire harness assembly includes a plurality of wire harness hoops 13 detachably connected to the collection rack leg 14, and the plurality of wire harness hoops 13 are spaced apart along the height direction of the collection rack leg 14, the cross-section of the wire harness hoops 13 is concave, and the wire harness hoops 13 are connected to the inner wall of the collection rack leg 14 by bolts.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
