Description

Technical Field

[0001] The utility model relates to the technical field of wire rod uncoiling equipment, in particular to a device for improving the running stability of an uncoiling trolley in a steel rolling wire rod production workshop. Background Art

[0002] In the high-speed wire rod production workshop for steel rolling, the finished product unloading cart automatically stops when it reaches the advance position signal, allowing the PF line's coil transport chain to release. If the unloading cart's advance position signal is falsely signaled due to a loose in-position switch, for example, the PF line's coil transport chain may release prematurely, causing the unloading cart to overturn, disrupting normal production, damaging equipment, and posing a safety hazard.

[0003] Since the unloading trolley is driven by a hydraulic motor, it will often cause a large overall shaking of the unloading trolley due to momentary stops, which can easily cause the forward positioning signal to be lost, affecting the automatic operation of the unloading trolley and often requiring manual intervention. Utility Model Content

[0004] Purpose of the utility model: In order to solve the problems existing in the prior art, the utility model provides a device for improving the operating stability of the unloading trolley in a steel wire production workshop, which reduces the probability of the PF line coil transport chain being hooked prematurely due to an erroneous signal, thereby causing the unloading trolley to overturn, and also avoids the violent shaking of the unloading trolley caused by instantaneous braking and the loss of the forward position signal.

[0005] The utility model is realized through the following technical solutions:

[0006] A device for improving the operational stability of a coil unloading trolley in a steel wire production workshop comprises a coil unloading trolley, a first induction signal switch, a trolley guide rail, a deceleration signal block, an in-position signal block, a trolley guide rail, a second induction signal switch, and a photoelectric tube. The running wheels on both sides of the coil unloading trolley are adapted to the trolley guide rail, and the running wheels on both sides of the coil unloading trolley are adapted to the trolley guide rail; the coil unloading trolley is provided with a first induction signal switch, and the induction signal switch passes through the deceleration signal block and the in-position signal block on its travel route; the trolley pit wall is provided with a second induction signal switch and a photoelectric tube; the first induction signal switch and the second induction signal switch form a double interlocking protection, and are connected to the PF line C-hook with a signal cable.

[0007] Preferably, it further comprises a trolley oil pipe, an induction signal cable and a drag chain, wherein the trolley oil pipe and the induction signal cable are both bound in the drag chain, and the drag chain is connected to the unloading trolley transmission system.

[0008] Preferably, the deceleration signal block and the in-position signal block are arranged between the rails on both sides of the trolley guide rail, and the first induction signal switch is connected to the trolley oil pipe with an induction signal cable.

[0009] Preferably, a bracket is further included, and the second induction signal switch is fixed to the wall of the trolley pit through the bracket.

[0010] Preferably, the trolley guide rail and the carriage guide rail are perpendicular to each other.

[0011] Preferably, the rolling wire production workshop unloading trolley operation stability improvement device can be provided in multiple sets, which are parallel to each other and perpendicular to the trolley guide rails.

[0012] The beneficial effects of the utility model are as follows:

[0013] This new system uses two parallel trolley position sensing devices to accurately determine the timing of PF wire hook removal, avoiding the risk of premature hook removal and the unloading trolley tipping over. By slowing the unloading trolley in advance, it prevents the unloading trolley from violently shaking due to instant braking and loss of the forward position signal. This simple and rational method improves the operational stability of the unloading trolley in the steel wire production workshop. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the utility model is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] Example 1

[0019] A device for improving the running stability of the unloading trolley in a steel wire production workshop, such as Figure 1 As shown, it includes a reel unloading trolley 1, a first induction signal switch 2, a trolley oil pipe 3, an induction signal cable 4, a trolley guide rail 5, a deceleration signal block 6, an in-position signal block 7, a trolley guide rail 8, a second induction signal switch 9, a photoelectric tube 10, and a drag chain 12. The running wheels on both sides of the reel unloading trolley 1 are adapted to the trolley guide rail 5, and the running wheels on both sides of the reel unloading trolley are adapted to the trolley guide rail 8. The reel unloading trolley 1 is provided with a first induction signal switch 2, and a deceleration signal block 6 and an in-position signal block 7 are provided in sequence on the travel route of the reel unloading trolley 1. The reel unloading trolley 1 decelerates when passing the deceleration signal block 6, and stops when passing the in-position signal block 7. Figure 2As shown, a second induction signal switch 9 and a photoelectric tube 10 are installed on the wall of the trolley pit. The induction distance is set appropriately so that they can detect whether the unloading trolley 1 is in place. The first induction signal switch 2 and the second induction signal switch 9 form a double interlock protection. Both are connected to the PF line C-type hook via an induction signal cable. The PF line can only be hooked when both simultaneously detect that the unloading trolley 1 is in place.

[0020] In a preferred solution, the trolley oil pipe 3 and the induction signal cable 4 are bound in a drag chain 12 and connected to the transmission system of the unloading trolley 1.

[0021] In a preferred solution, the deceleration signal block 6 and the in-position signal block 7 are arranged between the rails on both sides of the trolley guide rail 5, and the first induction signal switch 2 is connected to the trolley oil pipe 3 with an induction signal cable 4, thereby producing a braking effect.

[0022] A preferred solution, such as Figure 2 As shown, the second induction signal switch 9 is fixed to the wall of the trolley pit through a bracket 11.

[0023] In a preferred embodiment, the trolley guide rail 5 and the carriage guide rail 8 are perpendicular to each other.

[0024] A preferred solution is that the device for improving the running stability of the unloading trolley in the steel wire production workshop can be provided with multiple groups, and each group is arranged parallel to each other and perpendicular to the trolley guide rail 8.

[0025] During operation, the unloading trolley 1 moves from its starting point toward the gantry. When the first induction signal switch 2 on the unloading trolley passes the deceleration signal block 6, the unloading trolley 1 begins to decelerate, and when it reaches the in-position signal block 7, the unloading trolley 1 stops. A photoelectric tube 10 disposed on the wall of the trolley pit senses whether the unloading trolley 1 is in position. When the unloading trolley 1 reaches the hook-out position and the first induction signal switch 2 passes the in-position signal block 7, the PF line coil transport chain releases the hook.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments may be modified or some or all of the technical features thereof may be replaced with equivalents, and such modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the present invention.
