Description

Technical Field

[0001] This utility model relates to the field of railing equipment technology, and in particular to a telescopic isolation railing device. Background Technology

[0002] In the papermaking process, paper rolls are primarily used for winding and pressing paper. Through winding, paper rolls wind a continuous paper web into a roll shape, facilitating subsequent processing and transportation. Simultaneously, during pressing, paper rolls remove excess moisture from the paper, improving its quality and density. However, the weight of a paper roll after winding is considerable. When the roll is removed and lowered, the inertial impact is significant, potentially causing injury to personnel passing through the work area. Therefore, personnel must be kept outside the work area when removing the paper roll.

[0003] Currently, temporary retractable barriers are usually installed, which requires employees to manually restore the barriers frequently, which is laborious and time-consuming. Moreover, there are often cases where the barriers are forgotten to be installed due to negligence, increasing safety risks. Utility Model Content

Detailed Implementation

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] Please see Figures 1-4 A telescopic guardrail device includes a support base 100 and a drive mechanism. The support base 100 has a first receiving cavity 110, in which a first guardrail assembly 200 is movably connected. The first guardrail assembly 200 has a second receiving cavity 240, in which a second guardrail assembly 300 is movably connected. The drive mechanism is located on the support base 100 and includes a first drive assembly and a second drive assembly. The first drive assembly is connected to the first guardrail assembly 200, and the second drive assembly is connected to the second guardrail assembly 300. The first drive assembly and the second drive assembly are drively connected. The first drive assembly is at least used to drive the first guardrail assembly 200 to telescopically move in a first direction within the first receiving cavity 110, and simultaneously drives the second drive assembly to drive the second guardrail assembly 300 to telescopically move in the second receiving cavity 240 within the first receiving cavity 240.

[0025] In this embodiment, as Figure 1 , 3 As shown, the support base 100 is arranged vertically, wherein the first direction is horizontal. A first receiving cavity 110 is provided on one side of the support base 100. A first railing assembly 200 is telescopically disposed in the first receiving cavity 110, and the first railing assembly 200 extends entirely along the first direction. A first driving assembly is connected to the first railing assembly 200 and can drive the first railing assembly 200 to telescopically move relative to the support base 100 in the first direction. A second receiving cavity 240 is provided on the side of the first railing assembly 200 away from the support base 100. A second railing assembly 300 is telescopically disposed in the second receiving cavity 240, and the second railing assembly 300 extends entirely along the first direction. A second driving assembly is connected to the second railing assembly 300 and can drive the second railing assembly 300 to telescopically move relative to the first railing assembly 200 in the first direction. The first driving assembly and the second driving assembly are connected by transmission to ensure the consistency of movement of the first railing assembly 200 and the second railing assembly 300.

[0026] In practical operation, the device is placed on both sides of the working channel of the paper roller, with the first direction being perpendicular to the working channel. In the initial state, the first guardrail assembly 200 is housed in the first receiving cavity 110, and the second guardrail assembly 300 is housed in the second receiving cavity 240. This state is the retracted state, which reduces the placement space and allows personnel to pass through the working channel. When it is necessary to remove the paper roller, the first drive assembly starts to work, driving the first guardrail assembly 200 to extend out of the first receiving cavity 110 along the first direction. At the same time, the first drive assembly drives the second drive assembly to work, driving the second guardrail assembly 300 to extend out of the second receiving cavity 240 along the first direction. This state is the extended state, so that the first guardrail assembly 200 and the second guardrail assembly 300 play a role in isolating each other in the first direction, thereby preventing personnel from passing through the working channel when removing the paper roller. When the paper-taking roller finishes its operation, the first drive assembly drives the first guardrail assembly 200 to move in the opposite direction to retract and be accommodated in the first receiving cavity 110. At the same time, the first drive assembly drives the second drive assembly to move the second guardrail assembly 300 in the opposite direction to retract and be accommodated in the second receiving cavity 240, thus achieving the retracted state and allowing personnel to pass through the work passage.

[0027] In the above structure, automatic telescopic barriers are achieved by setting up a drive component and a telescopic first barrier assembly 200 and a second barrier assembly 300. The first barrier assembly 200 and the second barrier assembly 300 work together to isolate and block, increasing the isolation length and facilitating the use of longer work passages. In addition, by driving the first drive component and the second drive component together, the first barrier assembly 200 and the second barrier assembly 300 can telescopically move simultaneously, thereby improving telescopic efficiency, quickly completing the isolation and blocking, and improving safety.

[0028] Specifically, such as Figure 1 , 2As shown, the support 100 includes a first crossbeam 120 and a base support frame 140. The first crossbeam 120 extends along a first direction, and the base support frame 140 extends along a second direction. The first direction and the second direction are perpendicular. The interior of the first crossbeam 120 is a hollow structure to form a first receiving cavity 110. The support base 100 includes a second crossbeam 130, the extension direction of the second crossbeam 130 is a first direction, a plurality of first vertical beams 150 are provided between the second crossbeam 130 and the first crossbeam 120, and a first receiving groove extending along the first direction is provided in the second crossbeam 130. The first railing assembly 200 includes a third crossbeam 210 and a fourth crossbeam 220, both of which extend along the first direction. The third crossbeam 210 is movably connected in the first receiving cavity 110, and the fourth crossbeam 220 is movably connected in the first receiving groove. A second vertical beam 230 is fixedly connected between the ends of the third crossbeam 210 and the fourth crossbeam 220 away from the support base 100. The interior of the third crossbeam 210 is a hollow structure to form a second receiving cavity 240. The second railing assembly 300 includes a fifth crossbeam 310 and a sixth crossbeam 320, both of which extend along a first direction. A third vertical beam 330 is fixedly connected between the ends of the fifth crossbeam 310 and the sixth crossbeam 320 away from the support base 100. A second receiving groove extending along the first direction is provided in the fourth crossbeam 220. The fifth crossbeam 310 is movable within the second receiving cavity 240, and the sixth crossbeam 320 is movably connected within the second receiving groove. A vertical support 340 is fixed to the end of the fifth crossbeam 310 away from the support base 100. The vertical support 340 extends along a second direction, and the length of the vertical support 340 is less than the length of the base support frame 140.

[0029] In this embodiment, the support base 100 includes a first crossbeam 120 and a second crossbeam 130, wherein the first crossbeam 120 and the second crossbeam 130 are arranged in parallel and both extend along a first direction. The first crossbeam 120 is arranged vertically above the second crossbeam 130. A plurality of first vertical beams 150 extending vertically are fixedly connected between the first crossbeam 120 and the second crossbeam 130 to improve the overall structural strength and support stability of the support base 100. One first vertical beam 150 is connected to the first crossbeam 120. The first crossbeam 120 and the second crossbeam 130 are integrated at one end, thereby improving the structural strength. A base support frame 140 is also fixed to the lower side of the second crossbeam 130. The base support frame 140 extends vertically, i.e., in the second direction. The bottom end of the base support frame 140 is fixed to the ground or a work platform to provide support. The base support frame 140 may include multiple support rods, which are evenly distributed on the second crossbeam 130 to improve the support stability. Both the first crossbeam 120 and the second crossbeam 130 are tubular structures. The hollow part inside the first crossbeam 120 forms a first receiving groove, and the hollow part inside the second crossbeam 130 forms a first receiving cavity 110.

[0030] The first railing assembly 200 includes a third crossbeam 210 and a fourth crossbeam 220, wherein the third crossbeam 210 and the fourth crossbeam 220 are arranged in parallel and both extend along a first direction. Both the third crossbeam 210 and the fourth crossbeam 220 are tubular structures. The hollow portion inside the third crossbeam 210 forms a second receiving cavity 240, and the hollow portion inside the fourth crossbeam 220 forms a second receiving groove. The fourth crossbeam 220 is vertically positioned above the third crossbeam 210, and the outer diameter of the third crossbeam 210 is less than or equal to the inner diameter of the first receiving cavity 240, and the outer diameter of the fourth crossbeam 220 is less than or equal to the inner diameter of the first receiving groove, thereby allowing the first railing assembly to... The third crossbeam 210 of the rod assembly 200 is inserted into the first receiving cavity 110, and the fourth crossbeam 220 is correspondingly inserted into the first receiving groove. The second vertical beam 230 is fixedly connected between the ends of the third crossbeam 210 and the fourth crossbeam 220 away from the support base 100, so as to fix the third crossbeam 210 and the fourth crossbeam 220 together, improve the structural strength of the first railing assembly 200, and also effectively prevent the first railing assembly 200 from being completely stored in the support base 100. When the first railing assembly 200 moves telescopically relative to the support base 100, the third crossbeam 210 and the fourth crossbeam 220 move in the first receiving cavity 110 and the first receiving groove, respectively.

[0031] Accordingly, the second railing assembly 300 includes a fifth crossbeam 310 and a sixth crossbeam 320. The fifth crossbeam 310 and the sixth crossbeam 320 are arranged in parallel and both extend along the first direction. The fifth crossbeam 310 and the sixth crossbeam 320 are tubular structures. The sixth crossbeam 320 is arranged vertically above the fifth crossbeam 310. The outer diameter of the fifth crossbeam 310 is less than or equal to the inner diameter of the second receiving cavity 240, and the outer diameter of the sixth crossbeam 320 is less than or equal to the inner diameter of the second receiving groove, so that the fifth crossbeam 310 is inserted into the second receiving cavity 240, and the sixth crossbeam... The fifth and sixth horizontal beams 310 and 320 are respectively inserted into the second receiving slot. The third vertical beam 330 is fixedly connected between the ends of the fifth and sixth horizontal beams 310 and 320 away from the support base 100, so as to fix the fifth and sixth horizontal beams 310 and 320 together, improve the structural strength of the second railing assembly 300, and effectively prevent the second railing assembly 300 from being completely contained in the first railing assembly 200. When the second railing assembly 300 moves telescopically relative to the first railing assembly 200, the fifth and sixth horizontal beams 310 and 320 move in the second receiving cavity 240 and the second receiving slot, respectively. In addition, a vertical support 340 is fixed on the lower side of the fifth horizontal beam 310. The vertical support 340 extends vertically to improve the vertical blocking effect. In order not to affect the telescopic movement of the second railing assembly 300 in the horizontal direction, the length of the vertical support 340 is less than the length of the base support frame 140.

[0032] In the above structure, the support base 100, the first railing assembly 200 and the second railing assembly 300 are set as a double-row tubular structure, which increases the blocking area and blocking effect, while also improving the structural strength and the stability of the barrier. In addition, the double-row structure can also provide guidance and limit during telescopic movement, preventing deviation during telescopic movement.

[0033] Regarding the specific structure of the first driving component, such as Figure 3 , 4As shown, the first driving assembly includes a drive motor and a transmission screw 412. The axial direction of the transmission screw 412 is aligned with the first direction. The first railing assembly 200 is provided with a threaded slider 250, which is connected to the transmission screw 412. The output end of the drive motor is connected to the transmission screw 412 for at least driving the transmission screw 412 to rotate around its own axis, thereby causing the first railing assembly 200 to extend and retract in the first direction. In the specific structure of the second driving assembly, a first bevel gear 413 is fixed on the transmission screw 412. The first bevel gear 413 is coaxially arranged with the transmission screw 412. The second driving assembly includes a second bevel gear 421, a first gear 422, and a transmission rack 423. The second bevel gear 421 meshes with the first bevel gear 413, and the first gear 422 is fixed to the second bevel gear 421. The transmission rack 423 is fixedly connected to the second railing assembly 300, and the first gear 422 meshes with the transmission rack 423.

[0034] In this embodiment, the drive motor (not shown in the figure) can be disposed inside the first receiving cavity 110 or outside the first receiving cavity 110. In this embodiment, the drive motor is disposed outside the first receiving cavity 110. This can be achieved by additionally fixing a motor bracket (not shown in the figure) to the support base 100, mounting the drive motor on the motor bracket, and then disposing the transmission screw 412 along the first direction inside the first receiving cavity 110, with one end of the transmission screw 412 extending from the first receiving cavity 110 to the outside. The output end of the drive motor is connected to one end of the drive screw 412 extending out of the first receiving cavity 110, thereby driving the drive screw 412 to rotate around its own axis. A threaded slider 250 is fixed on the inner wall of the third crossbeam 210. When the third crossbeam 210 is inserted into the first receiving cavity 110, the threaded slider 250 engages with the drive screw 412. When the drive motor drives the drive screw 412 to rotate, it drives the threaded slider 250 to move along the first direction, thereby causing the third crossbeam 210 to extend and retract within the first receiving cavity 110. This structure is simple, has high movement accuracy, and facilitates better implementation of extension and retraction.

[0035] In addition, a first bevel gear 413 is fixed at the end of the transmission screw 412 away from the drive motor. The first bevel gear 413 is sleeved and fixed on the transmission screw 412, and the first bevel gear 413 and the transmission screw 412 are coaxially arranged, so that when the transmission screw 412 rotates, the first bevel gear 413 also rotates around its own axis. The second bevel gear 421 of the second drive assembly is installed on the upper side of the transmission screw 412 and meshes with the first bevel gear 413. The axial direction of the second bevel gear 421 is vertical. A first gear 422 is coaxially fixed on the upper side of the second bevel gear 421. A transmission rack 423 is fixedly connected to the inner wall of the fifth crossbeam 310. The transmission rack 423 extends along the first direction, and the first gear 422 meshes with the transmission rack 423.

[0036] In practical operation, when transitioning from a contracted state to an extended state, the drive motor drives the transmission screw 412 to rotate, causing the threaded slider 250 to move along the first direction. This causes the third crossbeam 210 to extend relative to the support seat 100 along the first direction. Simultaneously, the transmission screw 412 drives the first bevel gear 413 to rotate, which in turn drives the second bevel gear 421 to rotate. This, in turn, drives the first gear 422 and the transmission rack 423 to transmit power, causing the fifth crossbeam 310 to extend relative to the third crossbeam 210 along the first direction. When transitioning from an extended state to a contracted state, the drive motor drives the transmission screw to rotate in the opposite direction.

[0037] The above structure is achieved by connecting the transmission screw 412 and the threaded slider 250, and by connecting the first gear 422 and the transmission rack 423. The first drive assembly and the second drive assembly are connected by the first bevel gear 413 and the second bevel gear 421. The structure is simple, easy to operate, and has high transmission accuracy, effectively reducing transmission failures.

[0038] In addition, such as Figure 1 , 2 As shown, the support base 100 is equipped with a control module and a detector 520. The control module is connected to the first drive assembly, and the detector 520 is connected to the control module. The detector 520 is at least used to detect the passage of an object and transmit a signal to the control module. The control module is at least used to control the first drive assembly to extend the first railing assembly 200 when it receives a signal from the detector 520. The support base 100 is equipped with a warning assembly, which is connected to the control module. The warning assembly includes a warning light module 530 and a voice module 540.

[0039] In this embodiment, a control module and a detector 520 are also provided on the support base 100. The detector 520 can monitor the paper rollers via infrared. When the detector 520 detects a paper roller in the working channel that is about to be removed, it transmits a first signal to the control module. After receiving the first signal, the control module controls the drive motor to extend the first guardrail assembly 200 and the second guardrail assembly 300. When the detector 520 detects no paper roller in the working channel, it transmits a second signal to the control module. After receiving the second signal, the control module controls the drive motor to retract the first guardrail assembly 200 and the second guardrail assembly 300. By controlling the drive mechanism through the detector 520 and the control module to extend and retract the first guardrail assembly 200 and the second guardrail assembly 300, the automation effect and isolation effect are further improved. In addition, a warning component is also provided on the support base 100. The warning component includes a warning light module 530 and a voice module 540. When the control module receives the first signal, it controls the warning light module 530 to light up the corresponding light signal, and at the same time the voice module 540 plays the corresponding prompt voice, thereby effectively reminding personnel not to pass through the work passage, further improving the safety effect and effectively reducing safety risks.
