Description

Technical Field

[0001] The invention relates to process manufacturing, and in particular to a threading clamp and a method. Background Art

[0002] See also Figure 1 In the installation of greenhouse curtains, it is often necessary to pull wires 2 between the upper and lower chords of the truss 1, such as pulling curtain wires to support the curtain, or pulling steel cables to drive the curtain. If the truss 1 is high in the greenhouse, pulling the wires 2 between the upper and lower chords of the truss 1 is a troublesome project.

[0003] The conventional method is to use a long pole to support the wires 2 for insertion, or to rely on a person to climb up the truss 1 to insert the wires, because only one wire can be inserted one by one, which is both time-consuming and laborious.

[0004] Therefore, how to improve the efficiency of laying wires in the upper and lower chords of a truss is a problem to be solved in the art. Summary of the invention

[0005] In view of the existing technical problem of low efficiency in threading wires in trusses, the purpose of the present invention is to provide a wire threading clamp, which can pull multiple wires from one end of a greenhouse to the other end of the greenhouse in batches through the cooperation of a mobile lifting platform and a clamp assembly, thereby greatly improving the efficiency of threading wires in the trusses.

[0013] Furthermore, a movable end foot is provided at the bottom of one end of the sliding member, and at least one movable clamp is provided at the top in turn.

[0014] Furthermore, one end of the sliding member is inserted from the open end of the outer cavity and connected to the spring; the movable end foot at the bottom of the sliding member corresponds to the first limiting groove at the bottom of the outer cavity, and it can move axially within a certain stroke in the first limiting groove.

[0015] Each movable clamp at the top of the sliding member corresponds to a second limiting groove passing through the top of the outer cavity, and the movable clamp can move axially within a certain stroke in the second limiting groove.

[0016] Furthermore, each sliding chuck cooperates with each fixed chuck to form a set of clamp heads; the movable chuck moves axially back and forth in the second limiting groove relative to the fixed chuck, so as to achieve the tightness of the wire arranged in the middle of the chuck.

[0017] Furthermore, the transmission mechanism includes a cross transmission mechanism in which a first driving rod and a second driving rod are crossed and hingedly arranged, and its upper two ends are respectively hinged to the fixed end foot and the movable end foot of the outer cavity, and its bottom two ends are respectively hinged to the moving mechanism.

[0018] Furthermore, the moving mechanism includes a base, a first driving assembly, a second driving assembly and a pulley; the pulley is arranged at the bottom of the base to drive the base to slide on the ground;

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0038] In order to solve the technical problem of low efficiency in threading wires in trusses, the present invention provides a wire threading clamp, which can pass multiple wires through the trusses in batches in sequence through the cooperation of a mobile lifting platform and a clamp assembly, and pull them from one end of a greenhouse to the other end of the greenhouse, thereby greatly improving the efficiency of threading wires in the trusses.

[0039] It should be noted here that when describing this solution, the directions in the drawings are taken as examples in combination with the drawings, that is, the left and right directions in the drawings are used as the standard for description.

[0040] See also Figure 2-Figure 6 The threading clamp provided in this solution includes a clamp assembly 500, a lifting mechanism 300 and a moving mechanism 600; wherein the clamp assembly 500 can drive the wires to pass through the truss in sequence by cooperating with the lifting mechanism 300 and the moving mechanism 600.

[0041] See also Figure 2 The fixture assembly 500 includes two sets of fixtures; divided into a first fixture 510 and a second fixture 520; wherein the first fixture 510 and the second fixture 520 have the same structure; see Figure 3 Each fixture includes an outer cavity 100 and a sliding member 200 .

[0042] The outer cavity 100 is a rectangular hollow cavity, and the sliding member 200 is placed inside.

[0043] See also Figure 4 A spring 120 is disposed at one end of the inner part of the outer cavity 100; a port of the outer cavity 100 close to the spring 120 is closed by an end cover; and the other port away from the spring 120 is an open end.

[0044] At the same time, a fixed end foot 130 is provided at the bottom of one end of the outer cavity 100 close to the spring 120 ; and a first limiting groove 150 is provided at the bottom of the other end away from the spring 120 .

[0045] At least one fixing clamp 110 is sequentially disposed at the top of the outer portion of the outer cavity 100 , and a second limiting groove 140 is opened on the right side of each fixing clamp 110 and on the outer cavity.

[0046] The sliding member 200 is disposed inside the outer cavity 100; the shape of the sliding member 200 corresponding to the outer cavity 100 is also a rectangular body, see Figure 5 A movable end foot 220 is provided at the bottom of one end, and at least one movable clamp 210 is provided at the top in turn.

[0047] One end of the sliding member 200 is inserted from the open end of the outer cavity 100 and connected with the spring 120; the movable end foot 220 at the bottom of the sliding member 200 corresponds to the first limiting groove 150 at the bottom of the outer cavity 100, and it can perform axial movement within a certain stroke in the first limiting groove 150.

[0048] At the same time, each movable chuck 210 on the top of the sliding member 200 corresponds to the second limiting groove 140 passing through the top of the outer cavity 100, and the movable chuck 210 can perform axial movement of a certain stroke in the second limiting groove 140; each movable chuck 210 cooperates with the fixed chuck 110 to form a set of clamp heads.

[0049] The wire can be tightened or loosened by the movable clamp 210 moving back and forth axially relative to the fixed clamp 110;

[0050] When the sliding member 200 is driven to move to the right, the movable end foot 220 at the bottom of the sliding member 200 slides to the right in the first limiting groove 150 on the outer cavity 100. At the same time, the movable clamp 210 at the top of the sliding member 200 moves to the right relative to the fixed clamp 110 in the second limiting groove 140 on the outer cavity 100. At this time, the distance between the fixed clamp 110 and the movable clamp 210 is enlarged, and the wire can be placed in the middle of the clamp.

[0051] After placement, when the sliding member 200 is driven to move to the left, the movable end foot 220 at the bottom of the sliding member 200 slides to the left in the first limiting groove 150 on the outer cavity 100, and at the same time, the movable clamp 210 at the top of the sliding member 200 moves to the left relative to the fixed clamp 110 in the second limiting groove 140 on the outer cavity. At this time, the distance between the fixed clamp 110 and the movable clamp 210 is reduced. At the same time, the spring 120 provides a clamping force to clamp the wire placed between the fixed clamp 110 and the movable clamp 210.

[0052] Here, the number of the fixed clamps 110 on the outer cavity 100 and the movable clamps 210 on the sliding member 200 is not limited, and the specific number can be adjusted and determined according to actual conditions.

[0053] The first clamp 510 and the second clamp 520 formed by the outer cavity 100, the sliding member 200 and the spring 120 can achieve the clamping and loosening of the wire.

[0054] A lifting mechanism is provided below the first clamp 510 and the second clamp 520; the lifting mechanism comprises two sets of driving cross rods 300; wherein, see Figure 3The cross-drive rod 300 is cross-arranged by a first rod 310 and a second rod 320, and the cross portion is a hinged structure; wherein the first end of the first rod 310 is hinged to the movable end foot 220 under the outer cavity, and the second end can perform axial movement of a certain stroke on the moving mechanism 600; the first end of the second rod 320 is hinged to the fixed end foot 130 under the outer cavity, and the second end is hinged to the moving mechanism 600.

[0055] The cross transmission device is composed of two driving rods arranged crosswise, which can play two roles in the clamp assembly when applied:

[0056] First, when the second end of the first rod 310 of the cross-driving rod 300 is moved to the left, the first rod 310 drives the movable end foot 220 to move to the right in the first limiting groove 150; at the same time, the second rod 320 is synchronously driven to rotate to the right. At this time, the distance between the first rod 310 and the second rod 320 is enlarged, which will drive the two ends of the upper clamp to descend; at the same time, the opposite movement can drive the upper clamp to rise; at this time, pulling the cross-driving rod 300 can have the effect of lifting and lowering the clamp.

[0057] Second, the axial movement of the cross-drive rod 300 can be used to drive the sliding member 200 in the outer cavity 100 to move axially. Through the axial movement of the sliding member 200, the wire disposed in the chuck assembly can be loosened or tightened.

[0058] When the first rod 310 moves to the left, the sliding member 200 moves to the right while the clamp descends. At this time, the movable clamp 210 moves to the right relative to the fixed clamp 110. At this time, the distance between the fixed clamp 110 and the movable clamp 210 is enlarged, and the wire can be loosened, and vice versa, the wire can be clamped; here, pulling the cross-drive rod can drive the tightness of the clamp.

[0059] As described above, the clamp assembly consisting of two sets of clamps plus two sets of driving cross rods is symmetrically arranged on the moving mechanism 600 when in use.

[0060] The structure of the moving mechanism is not limited here, and the specific structure can be determined according to actual conditions.

[0061] The moving mechanism 600 is arranged at the bottom of the two crossed driving rods 300; for example, it includes a base, a first driving component, a second driving component and a pulley; the pulley is arranged at the bottom of the base, which can drive the base to slide on the ground, reduce friction, save time and effort.

[0062] In addition, two third limiting grooves are symmetrically arranged on the upper end surface of the base; wherein the first driving assembly and the second driving assembly are respectively arranged in the two third limiting grooves.

[0063] The second end of the second rod in the first chuck assembly passes through one of the third limiting grooves to be connected to the first drive assembly; the second end of the second rod in the second chuck assembly passes through another third limiting groove to be connected to the second drive assembly.

[0064] The first driving assembly and the second driving assembly can drive the cross driving rod, so that the second end of the second rod moves axially in the third limiting groove, thereby driving the sliding member to move axially.

[0065] The structures of the first driving assembly and the second driving assembly are not limited here. They can be driven by a hydraulic rod or by the rotation of a screw rod. The specific solution can be determined according to the actual situation.

[0066] The following example illustrates the working process of the present solution when in use; it should be noted that the following content is only a specific application example of the present solution and does not constitute a limitation on the present solution.

[0067] The threading clamp formed by the above scheme is used in conjunction with multiple groups of trusses when in use, and the multiple groups of trusses are arranged in sequence inside the greenhouse; wherein each group of trusses includes a truss upper chord 710 and a truss lower chord 720; the truss upper chord 710 and the truss lower chord 720 are arranged symmetrically up and down.

[0068] See also Figure 6-Figure 7 First, the first clamp 510 and the second clamp 520 are symmetrically arranged on the moving mechanism 600. The moving mechanism 600 moves the two sets of clamp assemblies to below the lower chord 720 of the truss. At this time, the second driving assembly drives the driving cross rod 300 on the second clamp 520 to move to the left. At this time, the second clamp 520 is driven by the transmission of the driving cross rod 300 to descend as a whole; at the same time, it drives the sliding member 200 to move to the right. At this time, the movable clamp 210 moves to the right relative to the fixed clamp 110, and the distance between the fixed clamp 110 and the movable clamp 210 is expanded; at this time, the rear end of the wire is placed in the second clamp 520.

[0069] Then the second driving assembly drives the driving cross rod 300 on the second clamp 520 to move to the right, and the second clamp 520 rises as a whole through the transmission of the driving cross rod 300; at the same time, it drives the sliding member 200 to move to the left, and the movable clamp 210 moves to the left relative to the fixed clamp 110, and the distance between the fixed clamp 110 and the movable clamp 210 is reduced; at this time, the wire placed in the second clamp 520 is clamped.

[0070] The moving mechanism 600 is driven, and the moving mechanism 600 drives the clamp to move, and drives the front end of the wire to pass through the middle of the upper and lower trusses until the first clamp 510 passes over the lower chord 720 of the truss, so that the first clamp 510 and the second clamp 520 are located on both sides of the truss and then stop.

[0071] Then the first driving assembly drives the driving cross rod 300 of the first clamp 510 to move to the right, and the first clamp 510 rises as a whole through the transmission of the driving cross rod 300; at the same time, it drives the sliding member 200 to move to the left, and at this time, the movable clamp 210 moves to the left relative to the fixed clamp 110, and the distance between the fixed clamp 110 and the movable clamp 210 is reduced; at this time, the first clamp 510 clamps the front end of the wire.

[0072] After clamping, the second clamp 520 is driven to descend and release the wire, and the moving mechanism 600 is driven to move forward so that the second clamp 520 passes through the lower chord 720 of the truss, and then rises to clamp the wire. In this way, the wire passes through the first group of trusses.

[0073] In this way, the first clamp 510 and the second clamp 520 perform staggered reciprocating motion up and down, so that a plurality of wires can be pulled from the other end of the greenhouse through the truss 1 to the other end of the greenhouse in batches.
