Description

Technical Field

[0001] The utility model relates to the technical field of tendon material conveying, in particular to tendon material conveying equipment. Background Art

[0002] As an important component of precast components, the production of steel cage requires steps such as fixed-length cutting of main reinforcement bars, upsetting, threading nuts, threading bars, and roll welding. Among them, before the bar threading step, a plurality of main reinforcement bars need to be sent to the bar threading equipment one by one through a steel bar conveyor for subsequent bar threading operations.

[0003] The existing steel bar conveyor includes a frame, a driving sprocket, a driven sprocket, a servo motor, and a conveyor belt. The driving sprocket and the driven sprocket are respectively installed on the frame and arranged at intervals in a front-back manner on the frame. The servo motor is installed on the frame and drives the driving sprocket to rotate. The conveyor belt is wound around the driving sprocket and the driven sprocket. A plurality of receiving grooves for receiving main reinforcement bars are provided along the rotation direction of the conveyor belt. During operation, the servo motor makes the conveyor belt perform a rotary motion through the cooperation of a speed reducer, the driving sprocket, and the driven sprocket to orderly convey the main reinforcement bars to the bar threading equipment. Since the main reinforcement bars of the steel cage are long and have a large self-weight, the conveyor belt is prone to sink and deform during transportation, which in turn leads to poor meshing between the conveyor belt and the main reinforcement bars. Summary of the Utility Model

[0004] The purpose of the utility model is to provide tendon material conveying equipment to solve the problems that the large self-weight of the main reinforcement bars of the steel cage causes the conveyor belt to sink and deform, and the conveyor belt and the main reinforcement bars have poor meshing.

[0032] In this article, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the drawings.

[0033] Embodiment 1

[0034] As Figure 1 , 2 shown, this embodiment provides a rib material conveying device, including: at least one chain conveying mechanism, a frame 1 supporting the chain conveying mechanism, and a power source for driving the operation of the chain conveying mechanism; wherein, the chain conveying mechanism includes a first driving wheel 5, a first driven wheel 3 provided on the frame 1, and a conveyor chain 2 that is rotationally connected to the first driving wheel 5 and the first driven wheel 3; wherein, the conveyor chain 2 includes a conveying side and a reset side, and the frame 1 is provided with a first tensioning mechanism for tensioning the conveyor chain 2, and at least one position-adjustable tensioning roller 63 is provided between the conveying side and the reset side of the tensioning mechanism.

[0035] Specifically, the power source drives the operation of the chain conveyor mechanism, that is, the power source drives the first driving wheel 5 to rotate, causing the conveyor chain 2 to perform a rotary motion to transport the reinforcing bars from one station to the next station. The first driven wheel 3 supports the conveyor chain 2 and rotates under the drive of the conveyor chain 2. During the conveying process, the tensioning roller 63 pushes against the first driving wheel 5 or the first driven wheel 3 or the conveyor chain 2 to force the first driving wheel 5 or the first driven wheel 3 to shift or force the conveyor chain 2 to deform to tension the conveyor chain 2, solving the problem that the conveyor chain 2 sinks and deforms due to the self-weight of the reinforcing bars during the transportation of the reinforcing bars, resulting in poor meshing of the chain. Preferably, the tensioning roller 63 pushes against the conveyor chain 2 to force the conveyor chain 2 to deform to tension the conveyor chain 2. More preferably, the tensioning roller 63 pushes against the reset side of the conveyor chain 2 to tension the conveyor chain 2. Specifically, the side of the conveyor chain 2 for transporting the reinforcing bars is called the conveying side of the conveyor chain 2, and the side of the conveyor chain 2 opposite to its conveying side is called the reset side of the conveyor chain 2. The tensioning roller 63 pushes against the reset side of the conveyor chain 2 instead of the conveying side, thus avoiding the deformation of the conveying side of the conveyor chain 2 from affecting the transportation of the reinforcing bars.

[0036] Further, the first tensioning mechanism includes a tensioning roller connecting seat 64 movably installed on the frame 1. The frame 1 is provided with a first position adjusting component for adjusting the installation position of the tensioning roller connecting seat 64. The tensioning roller 63 is installed on the tensioning roller connecting seat 64. The first position adjusting component drives the tensioning roller connecting seat 64 to move along the frame 1 so that the tensioning roller 63 pushes against the reset side of the conveyor chain 2 to tension the conveyor chain 2.

[0037] Further, the frame 1 includes a main frame 11 and a sub-frame 12. The chain conveyor mechanism is installed on the main frame 11, and the tensioning roller connecting seat 64 is installed on the sub-frame 12. The first position adjusting component includes a abutment seat 65 provided on the sub-frame 12. The abutment seat 65 is provided with a through threaded hole, and a screw rod 66 is screwed into the abutment seat 65. The end of the screw rod 66 abuts against the tensioning roller connecting seat 64. The length direction of the screw rod 66 is inclined to the length direction of the conveyor chain 2. The sub-frame 12 is installed on the main frame 11, and an external power source drives the screw rod 66 to rotate. Since the abutment seat 65 is screwed with the screw rod 66, the screw rod 66 makes a feeding motion under the drive of the external power source, pushing the tensioning roller connecting seat 64 to move, thereby driving the tensioning roller 63 to push against the reset side of the conveyor chain 2 to tension the conveyor chain 2. The external power source can be any one of manual, electric or other power sources. The length of the screw rod 66 is inclined to the length direction of the conveyor chain 2 to ensure that the screw rod 66 can drive the tensioning roller 63 on the tensioning roller connecting seat 64 to push against the reset side of the conveyor chain 2 when making a feeding motion. Among them, all the chain conveyor mechanisms can be installed on a large frame, or the frame can include multiple frame units, and one chain conveyor mechanism is installed on one frame unit, without specific limitation, as long as the chain conveyor mechanism can be installed to connect two stations.

[0038] Further, the screw rod 66 is screwed with a locking nut 67; when it is necessary to fix the screw rod 66, the screw rod 66 is locked by the locking nut 67. Specifically, by screwing the locking nut 67 so that the locking nut 67 abuts against the abutting seat 65, the screw rod 66 is locked by the frictional force between the locking nut 67 and the abutting seat 65, preventing the screw rod 66 from loosening by itself and affecting its tensioning effect.

[0039] Further, a first guiding assembly is provided between the tensioning roller connecting seat 64 and the frame 1. The first guiding assembly is used to guide the tensioning roller connecting seat 64 so that the tensioning roller connecting seat 64 can move along a predetermined direction under the pushing of the screw rod 66.

[0040] Further, the first guiding assembly includes a guiding groove 61 and a guiding column 62 movably placed in the guiding groove 61. The length direction of the guiding groove 61 is parallel to the length direction of the screw rod 66. One of the tensioning roller connecting seat 64 and the frame 1 is provided with the guiding groove 61, and the other of the tensioning roller connecting seat 64 and the frame 1 is provided with the guiding column 62. The moving direction of the tensioning roller connecting seat 64 is restricted by the cooperation between the guiding groove 61 and the guiding column 62. Preferably, a locking head is provided at the end of the guiding column 62 for locking the guiding column 62 in the guiding groove 61.

[0041] Further, a plurality of material bearing members 21 are arranged at intervals along the conveying direction of the conveying chain 2. The material bearing members 21 and the conveying chain 2 form a limiting groove, and the material bearing members 21 are bent toward the conveying direction. During the conveying of the rib material, the limiting groove formed by the material bearing members 21 and the conveying chain 2 is used to limit the rib material and drive the rib material to move along the conveying direction. The material bearing members 21 are bent toward the conveying direction to increase the contact area between the material bearing members 21 and the rib material, enhance the stability of rib material conveying, and prevent the rib material from slipping out of the limiting groove during conveying.

[0042] Further, a wear-resistant coating is provided on the outer peripheral surface of the conveying chain 2; and / or, a wear-resistant coating is provided on the outer peripheral surface of the tensioning roller 63. During the conveying of the rib material, there is a problem of friction between the conveying chain 2 and the rib material and between the tensioning roller 63 and the conveying chain 2. The setting of the wear-resistant coating can improve the wear resistance of the conveying chain 2 and the tensioning roller 63 and ensure the service life. The wear-resistant coating is preferably polytetrafluoroethylene.

[0043] Embodiment 2

[0044] For the parts in this embodiment that are the same as those in Embodiment 1, the same reference numerals are given and the same text descriptions are omitted.

[0045] As Figures 3 - 6 shown, compared with Embodiment 1, the rib material conveying device provided in this embodiment also has such a different structural design:

[0046] It may be a chain conveyor mechanism connected to a power source. However, it is preferably that two or more reinforcing bar conveying devices are arranged at intervals along the axial direction of the main transmission shaft 82 of the power source, and the first driving wheels 5 of each rotary conveying structure are all connected to the main transmission shaft 82, and the frame 1 of at least one of the reinforcing bar conveying devices is installed with the power source. When dealing with relatively long reinforcing bars, it will be difficult for each chain conveyor mechanism to operate synchronously and stably to effectively convey the reinforcing bars. Controlling all the chain conveyor mechanisms to operate synchronously through the main transmission shaft 82 can stably convey the reinforcing bars. Moreover, driving multiple chain conveyor mechanisms to convey the reinforcing bars by one power source is beneficial to cost reduction and energy conservation.

[0047] Furthermore, the power source includes a second driving wheel 72, a second driven wheel 73 connected to the main transmission shaft 82, and a transmission chain 71 connecting the second driving wheel 72 and the second driven wheel 73; the frame 1 is provided with a second tensioning mechanism. The second tensioning mechanism includes a second driving wheel connecting seat 74 movably installed on the frame 1 and used for installing the second driving wheel 72. The frame 1 is provided with a second position adjusting component for adjusting the installation position of the second driving wheel connecting seat 74, and a second guiding component is arranged between the second driving wheel connecting seat 74 and the frame 1. The power source includes a second driving wheel 72 and a rotary power source connected to the second driving wheel 72. The rotary power source drives the second driving wheel 72 to rotate, thereby driving the second driven wheel 73 to rotate, driving the transmission chain 71 to perform a rotary motion, and transmitting the power from the rotary power source to the moving second driven wheel 73, so as to transmit the power source to the main transmission shaft 82. The structure of the second position adjusting component is the same as that of the first position adjusting component. Of course, they may also be different, without specific limitation, as long as the position of the second driving wheel connecting seat 74 can be adjusted. The structure of the second guiding component is the same as that of the first guiding component. Of course, they may also be different, without specific limitation, as long as the moving direction of the second driving wheel connecting seat 74 can be restricted. The rotary power source can be any one of a motor, a motor or other devices that can output rotational power.

[0048] Furthermore, the first driven transmission wheels of each rotary conveying structure are connected with a driven transmission shaft 81 parallel to the main transmission shaft 82. The driven transmission shaft 81 is used to ensure that the rotational speeds of all the first driven wheels 3 are the same, and further ensure that the rotational speeds of all the conveying chains 2 are the same, so as to ensure that all the conveying chains 2 can maintain synchronism when transporting the same reinforcing bar, and avoid the inclination of the reinforcing bar caused by the non-synchronism of all the conveying chains 2.

[0049] Further, a base 9 is provided at the bottom of the rack 1, and the rack 1 and the base 9 are connected by fasteners. By providing the base 9, the height between the racks 1 can be adjusted, so that the height between the racks 1 can be kept consistent, making the ribs always horizontal and enhancing the stability during transportation. Specifically, after adjusting the height between the base 9 and the rack 1 to a preset height, the position of the base 9 and the rack 1 is fixed by fasteners. The fasteners only need to be able to fix the relative position of the base 9 and the rack 1, and there is no limitation on its specific structure. For example Figure 1 As shown, a structure of a fastener is provided here. The fastener includes a mounting screw 91 mounted on the base 9. A through hole adapted to the mounting screw 91 is provided at the bottom end of the rack 1. Limiting nuts 92 are provided on both sides of the mounting screw 91 located on the rack 1. The relative position of the base 9 and the rack 1 is fixed by the abutment of the limiting nuts 92 against the rack 1.

[0050] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
