Description

Technical Field

[0001] This utility model relates to the field of fall prevention technology, specifically a crossbar type anti-fall device for belt conveyors. Background Technology

[0002] In coal mining, belt conveyors are commonly used to transport ore. Also known as belt conveyors or belt conveyors, they are devices that use a continuous, circulating belt to transport materials. Due to the weight of the ore, side guardrails need to be installed on the crossbars on both sides of the belt conveyor to prevent it from falling.

[0003] Currently, side guardrails used to prevent falls are mainly made of pole-shaped or tubular guardrails. Due to the large impact force in mines, pole-shaped guardrails are often deformed or tubular guardrails are dented. Therefore, side guardrails need to be replaced regularly, resulting in poor durability and aesthetics. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a crossbar type anti-fall device for belt conveyors. This device mainly uses steel wire to intercept the side of the belt conveyor. The steel wire is not easily deformed or dented after being hit by falling objects, thus making it more durable and aesthetically pleasing.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is implemented as follows:

[0006] A crossbar type anti-fall device for belt conveyors is fixed on the crossbars on the left and right sides of the belt conveyor. It is mainly used to prevent the conveyed objects from falling. It includes a double crossbar reinforcement assembly, on which multiple side guard bars are vertically fixed at even intervals.

[0007] The side guard bar has multiple evenly distributed lead wire openings along its axial direction, and a side guard steel wire is horizontally threaded through each lead wire opening;

[0008] Steel balls are fixed at both ends of the side protection steel wire. The diameter of the steel balls is larger than the opening diameter of the lead wire. The steel balls abut against the two side protection rods at the outermost end of the double cross seat reinforcement assembly, and the side protection steel wire is in a state of tension and straightening.

[0009] Using the above solution, the device mainly uses steel wire to intercept the sides of the belt conveyor. The steel wire is not easily deformed or dented after being hit by falling objects, thus making it more durable and aesthetically pleasing.

[0010] As a preferred embodiment of a crossbar type belt conveyor anti-fall device, the double crossbar reinforcement assembly includes an upper crossbar located above and a lower crossbar located below. The upper crossbar and the lower crossbar are parallel to each other and are fixedly connected by multiple evenly distributed reinforcement seats.

[0011] To further enhance the reinforcement effect of the side guardrail using the above solution, two sets of cross braces are used to fix the side guardrail together, which will result in better reinforcement of the bottom of the side guardrail.

[0012] As a preferred embodiment of a crossbar type belt conveyor anti-fall device, a tensioning rod is also provided between each two adjacent side guard bars, which is rotatably installed on the double cross seat reinforcement assembly. The tensioning rod has a tensioning groove running through its interior, and all the side guard steel wires are threaded through the tensioning groove.

[0013] By adopting the above solution, in order to adjust the tension of the side protection wire during use, the side protection wire can be tightened simultaneously from two directions by rotating the tensioning rod, making it more flexible during use.

[0014] In a preferred embodiment of a crossbar-type belt conveyor anti-fall device, the bottom end of the tensioning bar is concentrically connected to a turntable.

[0015] By adopting the above solution, in order to facilitate the rotation of the tensioning rod, a rotating turntable can be used, which will make it easier to rotate the tensioning rod.

[0016] As a preferred embodiment of a fall prevention device for a crossbar type belt conveyor, four locking nuts are installed on the outer side of the tensioning rod through threaded engagement, two of which are located above and below the upper crossbar, and the other two are located above and below the lower crossbar.

[0017] To ensure the tensioning rod remains fixed after rotation, four locking nuts are used to engage with the upper and lower cross seats, thus locking the tensioning rod.

[0018] In a preferred embodiment of a crossbar-type belt conveyor anti-fall device, the upper and lower surfaces of the locking nut are provided with anti-slip parts; wherein, the anti-slip parts are several evenly distributed surface protrusions.

[0019] In order to prevent the lock nut from loosening, the above solution is adopted. Surface protrusions are provided on the upper and lower surfaces of the lock nut to increase the friction after the two come into contact, thereby preventing the lock nut from loosening.

[0020] After adopting the above technical solution, the beneficial effects of this utility model are:

[0021] 1. This device mainly uses steel wire to intercept the sides of the belt conveyor. The steel wire is not easily deformed or dented after being hit by falling objects, thus making it more durable and aesthetically pleasing.

[0022] 2. To further enhance the reinforcement effect of the side guardrail, two sets of cross braces are used to fix the side guardrail together, which will make the bottom of the side guardrail more reinforced.

[0023] 3. To adjust the tension of the side protection wire during use, the side protection wire can be tightened simultaneously from two directions by rotating the tensioning rod, making it more flexible during use;

[0024] 4. To facilitate the rotation of the tensioning rod, a rotating turntable can be used, which will make rotating the tensioning rod less strenuous;

[0025] 5. To ensure the tensioning rod is fixed after rotation, four locking nuts are used to abut against the upper and lower cross seats respectively, which can lock the tensioning rod.

[0026] 6. To prevent the lock nut from loosening, surface protrusions are provided on the upper and lower surfaces of the lock nut to increase the friction after they come into contact, thereby preventing the lock nut from loosening. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1 to 6 As shown, a crossbar-type anti-fall device for a belt conveyor is fixed to the crossbars on both sides of the belt conveyor. It is primarily used to prevent the conveyed material from falling. The device includes a double-crossbar reinforcement assembly, on which multiple evenly spaced side guard bars 1 are vertically fixed. Multiple evenly distributed guide holes 2 are opened along the axial direction of each side guard bar 1, and a side guard wire 3 is horizontally threaded through each guide hole 2. Steel balls 4 are fixed to both ends of each side guard wire 3. The diameter of the steel balls 4 is larger than the opening diameter of the guide hole 2. The steel balls 4 abut against the two outermost side guard bars 1 of the double-crossbar reinforcement assembly, and the side guard wire 3 is in a taut and taut state. This device mainly uses steel wire to intercept the sides of the belt conveyor. The steel wire is not easily deformed or dented after being impacted by falling objects, thus providing better durability and aesthetics.

[0039] like Figure 4 As shown, the double-horizontal-seat reinforcement assembly includes an upper horizontal seat 5 located at the top and a lower horizontal seat 6 located at the bottom. The upper horizontal seat 5 and the lower horizontal seat 6 are parallel to each other and are fixedly connected by multiple evenly distributed reinforcement seats 7. In order to further improve the reinforcement effect of the side guard rod 1, two sets of horizontal seats are used to fix the side guard rod 1 together, so that the bottom reinforcement effect of the side guard rod 1 will be better.

[0040] like Figures 7 to 8As shown, a tensioning rod 8, rotatably mounted on the double cross-seat reinforcement assembly, is also provided between each pair of adjacent side guard rods 1. A tensioning groove 9 is provided inside the tensioning rod 8, and all the side guard steel wires 3 are threaded through the tensioning groove 9. In order to adjust the tension of the side guard steel wires 3 during use, the side guard steel wires 3 can be tightened simultaneously from two directions by rotating the tensioning rod 8, making them more flexible during use.

[0041] like Figure 8 As shown, a turntable 10 is concentrically connected to the bottom end of the tensioning rod 8. To facilitate the rotation of the tensioning rod 8, the turntable 10 can be rotated, making it easier to rotate the tensioning rod 8.

[0042] like Figure 8 As shown, four locking nuts 11 are threadedly installed on the outer side of the tensioning rod 8. Two locking nuts 11 are located above and below the upper cross seat 5, respectively, and the other two locking nuts 11 are located above and below the lower cross seat 6, respectively. To ensure the tensioning rod 8 is fixed after rotation, the four locking nuts 11 abut against the upper cross seat 5 and the lower cross seat 6, respectively, thus locking the tensioning rod 8.

[0043] The upper and lower surfaces of the locking nut 11 are provided with anti-slip parts; wherein, the anti-slip parts are several evenly distributed surface protrusions. In order to prevent the locking nut 11 from loosening, the surface protrusions on the upper and lower surfaces of the locking nut 11 can increase the friction after the two come into contact, thereby preventing the locking nut 11 from loosening.

[0044] The working principle of this utility model:

[0045] In application, the double crossbar reinforcement assembly is fixedly installed on the crossbars on the left and right sides of the belt conveyor with bolts and nuts. Depending on the volume of the conveyed ore, the side protection steel wire 3 can be introduced into the corresponding lead-in port 2 so that the height of the side protection steel wire 3 is just higher than the volume of the ore. The side protection steel wire 3 is not easily deformed or dented after being hit by the ore, thus making it more durable and aesthetically pleasing.

[0046] In the above-mentioned use process, in order to adjust the tightness of the side protection steel wire 3 during use, the side protection steel wire 3 can be tightened simultaneously from two directions by rotating the tension rod 8. Then, the four locking nuts 11 are used to abut against the upper cross seat 5 and the lower cross seat 6 respectively, which can lock the tension rod 8 and make it more flexible during use.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
