[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0025] According to an embodiment of the present utility model, on the one hand, as Figures 1 to 4As shown, a hose installation device for a telescopic arm is provided, comprising a hose rail assembly 2, a telescopic arm 1 and a connecting assembly 5. The hose rail assembly 2 is arranged on one side of the telescopic arm 1, and is telescopically moved synchronously with the telescopic arm 1 through the connecting assembly 5. The connecting assembly 5 comprises a connecting plate 501 and a bracket 502, wherein a first end of the connecting plate 501 is connected to the hose rail assembly 2, the bracket 502 is connected to the telescopic arm 1, and a second end of the connecting plate 501 is arranged close to the bracket 502, and a moving space is provided between the second end of the connecting plate 501 and the bracket 502 in the vertical and / or horizontal direction.

[0026] The hose slide rail assembly 2 and the telescopic arm 1 are connected by setting a connecting plate 501 and a bracket 502, and a moving space is formed between the connecting plate 501 and the bracket 502 in the vertical direction and the horizontal direction respectively, so that the connecting plate 501 has a certain movable margin relative to the bracket 502. Therefore, when the telescopic arm 1 generates a certain deflection and bends, the hose slide rail assembly 2 can adapt to the displacement caused by the deflection of the telescopic arm 1 under the action of the moving space, thereby avoiding the deformation or damage of the hose slide rail assembly 2 after the telescopic arm 1 bends due to deflection when the hose slide rail assembly 2 and the telescopic arm 1 are fixedly connected.

[0027] Specifically, in this embodiment, the telescopic arm 1 has a plurality of telescopic arm units 101, and the plurality of telescopic arm units 101 are plug-connected in sequence.

[0028] Specifically, in this embodiment, the hose slide rail assembly 2 has a plurality of slide rail units 201, and the plurality of slide rail units 201 are plugged in sequence, and the plurality of slide rail units 201 are connected one-to-one with a plurality of telescopic arm units 101, so that the slide rail units 201 and the telescopic arm units 101 can telescope synchronously.

[0029] Specifically, in the present embodiment, the slide rail unit 201 is a square tube structure. Of course, in other alternative implementations, the slide rail unit 201 may also use a rectangular tube, a round tube or other structures.

[0030] Specifically, in this embodiment, Figure 2 As shown, the bracket 502 includes a protrusion extending from the telescopic arm unit 101 to the slide rail unit 201, and the protrusion is provided with a connection port facing the connection plate 501, and the second end of the connection plate 501 passes through the connection port and is inserted into the interior of the protrusion.

[0031] Specifically, in this embodiment, the second end of the connecting plate 501 is inserted into the interior of the protrusion and forms a vertical moving space with the gap between the upper wall and the lower wall of the protrusion. When the slide rail unit 201 jumps and displaces, the slide rail unit 201 can produce a certain movement within the set vertical moving space, which is conducive to correcting the movement of the slide rail unit 201.

[0032] Specifically, in this embodiment, the connecting plate 501 is connected to the slide rail unit 201 by welding.

[0033] It is worth noting that if Figures 1 to 4 As shown, in this embodiment, the bracket 502 is arranged corresponding to the extended end of the telescopic arm unit 101, and the connecting plate 501 is arranged corresponding to the extended end of the slide rail unit 201. The bracket 502 and the connecting plate 501 are arranged corresponding to the extended ends of the telescopic arm unit 101 and the slide rail unit 201, respectively, so as to avoid the setting of the bracket 502 and the connecting plate 501 affecting the retracted position of the telescopic arm unit 101 and the slide rail unit 201, and for the hose hanging assembly 3 located on one slide rail unit 201, the connecting plate 501 is prevented from obstructing the moving path of the hose hanging assembly 3, so that its moving distance can be extended as much as possible, thereby improving the flexibility of the hose 6 hanging.

[0034] It is worth further explaining that Figure 2 In the present embodiment, the connecting plate 501 is installed corresponding to the extended end of the slide rail unit 201, and the movable distance of the hose hanging assembly 3 on the slide rail unit 201 can be approximately equal to the length of the entire slide rail unit 201; and if the connecting plate 501 is set to correspond to other positions of the slide rail unit 201, such as the middle position of the slide rail unit 201 along the length direction, then the movable distance of the hose hanging assembly 3 on the slide rail unit 201 is only half of the length of the entire slide rail unit 201, which makes it inconvenient for the hose 6 to move simultaneously with the telescopic arm unit 101 and the slide rail unit 201.

[0035] Specifically, in this embodiment, the extended end of the telescopic arm unit 101 is an end protruding from the plug-in position after being inserted into the adjacent telescopic arm unit 101, that is, Figure 3 The middle telescopic arm unit 101 is located at one end on the right side, and the extended end of the slide rail unit 201 is the end protruding from the plug-in position after being inserted into the adjacent slide rail unit 201, that is, Figure 3 The middle slide rail unit 201 is located at one end of the right side.

[0036] In one embodiment, the connecting component 5 also includes a second fastener 503. A strip hole is opened on the connecting plate 501 near the second end. The strip hole is opened along the extension direction of the connecting plate 501. A moving space in the horizontal direction is formed in the strip hole. The second fastener 503 is connected to the bracket 502 and inserted into the strip hole.

[0037] Specifically, in this embodiment, the strip-shaped hole is extended along the connecting line direction between the first end and the second end of the connecting plate 501. Figure 4 The direction perpendicular to the drawing surface (also referred to as the “horizontal direction”).

[0038] Specifically, in this embodiment, the second fastener 503 includes a bolt and a second nut. The bolt penetrates the upper and lower walls of the protrusion and the strip hole at the same time. The second nut is threadedly connected to the bolt and abuts against the outer wall of the protrusion. When the slide rail unit 201 jumps and displaces, the slide rail unit 201 can produce a certain movement in the horizontal moving space formed in the strip hole, which is conducive to correcting the displacement of the slide rail unit 201.

[0039] In one embodiment, the hose installation device of the telescopic arm also includes a hose hanging assembly 3, which is sleeved on the outside of the hose slide rail assembly 2 and can be moved along the telescopic direction of the telescopic arm 1. The hose hanging assembly 3 is suitable for hanging and connecting with the hose 6.

[0040] In one embodiment, Figure 3 and Figure 4 As shown, the hose hanging assembly 3 includes a mounting structure 301 and a flexible cable 302 .

The plurality of rollers 3012 are in rolling contact with the outer wall surface of the hose slide rail assembly 2. The first end of the flexible cable 302 is connected to the mounting frame 3011. By arranging the roller 3012 to be in rolling contact with the hose slide rail assembly 2, the friction force is reduced, so that the mounting frame 3011 slides more smoothly on the hose slide rail assembly 2. The roller 3012 can effectively prevent the mounting frame 3011 from deflecting or shaking when sliding, thereby improving the reliability of the hose hanging assembly 3, reducing the wear of the mounting frame 3011, and increasing the service life of the mounting frame 3011.

[0043] In one embodiment, Figures 1 to 4As shown, the mounting frame 3011 includes a first mounting shaft 30111, a second mounting shaft 30112 and a first fastener 30113. Several first mounting shafts 30111 are arranged on the outside of the hose slide rail assembly 2, and several second mounting shafts 30112 are arranged on the outside of the hose slide rail assembly 2. Along the circumference of the hose slide rail assembly 2, the first mounting shaft 30111 and the second mounting shaft 30112 are alternately arranged in sequence. The rollers 3012 are respectively sleeved on the first mounting shaft 30111 and the second mounting shaft 30112. Both ends of the first mounting shaft 30111 have connecting parts. Several first fasteners 30113 are arranged, and each first fastener 30113 connects the connecting part and the second mounting shaft 30112.

[0044] Specifically, in this embodiment, the first fastener 30113 includes a screw and a first nut, and two first nuts are correspondingly provided to one screw. The screw simultaneously passes through the connecting parts of the two first installation shafts 30111 and the second installation shaft 30112 located between the two connecting parts. The two first nuts are respectively threadedly connected to the two ends of the screw, and the two first nuts are respectively abutted and fixed to the connecting parts of the two first installation shafts 30111.

[0045] Specifically, in this embodiment, Figure 2 As shown, corresponding to the slide rail unit 201 with a square tube structure, the first installation axis 30111 and the second installation axis 30112 are both provided with two installation frames 3011 which form a rectangular structure.

[0046] Of course, in other alternative embodiments, the number of the first mounting shaft 30111 and the second mounting shaft 30112 can be set correspondingly according to the specific shape of the slide rail unit 201.

[0047] It is worth noting that when the slide rail unit 201 is a circular tube structure, the mounting frame 3011 can be configured as a ring frame.

[0048] In one embodiment, Figures 1 to 4 As shown, the mounting frame 3011 also includes a hanging plate 30114, which is connected to the first mounting shaft 30111 and / or the second mounting shaft 30112, and the hanging plate 30114 is arranged corresponding to the bottom of the hose slide rail assembly 2. The hanging plate 30114 is provided with a hanging hole, and the first end of the flexible cable 302 is connected to the hanging hole.

[0049] In one embodiment, Figures 1 to 4 As shown, one or more hose hanging assemblies 3 are arranged on the hose slide rail assembly 2. By arranging a plurality of hose hanging assemblies 3, it is advantageous to fix the hose 6 at multiple positions, thereby enhancing the stability of the hose 6 hanging and enhancing the flexibility of the hose 6 telescopic movement.

[0050] In one embodiment, Figures 1 to 4 As shown, the hose installation device of the telescopic arm also includes a shield 4, which is connected to the telescopic arm 1 and is suitable for simultaneously shielding at least part of the hose 6 and at least part of the hose slide rail assembly 2. By providing the shield 4, the protection of the hose 6 is further enhanced to prevent the hose 6 from being damaged and affecting normal operation.

[0051] According to an embodiment of the present utility model, on the other hand, a construction equipment is provided, including the above-mentioned hose installation device of the telescopic arm.
