[0030] 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.

[0031] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0033] Combine the following Figures 1 to 4 , describing a pipeline installation structure and construction equipment of a telescopic arm in an embodiment of the utility model.

[0034] On the one hand, if Figure 1 and Figure 2 As shown, the utility model provides a pipeline installation structure 100 of a telescopic boom, comprising a main boom 10 , a first telescopic arm 20 , a slide rail portion 30 , and a slide assembly 40 .

[0035] The first telescopic arm 20 is disposed in the main boom 10 so that the first telescopic arm 20 has an extended state and a retracted state. When the first telescopic arm 20 is in the extended state, the length of the telescopic arm is increased, and when the first telescopic arm 20 is in the retracted state, it is convenient to store and reduce the occupied space. One end of the slide assembly 40 is connected to the first telescopic arm 20.

[0036] It should be noted that a single-stage telescopic arm or a multi-stage telescopic arm may be provided in the main boom 10. When the telescopic arm in the main boom 10 has only one stage, it is the first telescopic arm 20. When the telescopic arm in the main boom 10 has multiple stages, the first telescopic arm 20 is the telescopic arm with the smallest cross-sectional size.

[0037] For example, Figure 3As shown, the pipeline installation structure 100 of the telescopic boom also includes at least one second telescopic arm 50. The second telescopic arm 50 is located in the main boom 10 and is arranged between the main boom 10 and the first boom 20. At this time, one end of the slide assembly 40 is also connected to the first telescopic arm 20.

[0038] If the number of the second telescopic arm 50 is one, the second telescopic arm 50 is inserted into the main boom 10, and the first telescopic arm 10 is inserted into the second telescopic arm 50, which is a two-stage telescopic arm structure.

[0039] If there are multiple second telescopic arms 50, the multiple second telescopic arms 50 are sequentially inserted and inserted into the main boom 10. For example, a second telescopic arm 50 close to the main boom 10 (i.e., with the largest cross-sectional size) is the outermost one, and a second telescopic arm 50 far from the main boom 10 (i.e., with the smallest cross-sectional size) is the innermost one, and the first telescopic arm 50 is inserted into the innermost second telescopic arm 50.

[0040] The slide rail portion 30 is disposed on the outside of the main boom 10 along the length direction of the main boom 10, one end of the slide assembly 40 is slidably connected to the slide rail portion 30, and the other end of the slide assembly 40 is connected to the first telescopic arm 20. The first telescopic arm 20 can drive the connected slide assembly 40 to extend or retract synchronously along the length direction of the main boom 10. The slide assembly 40 is also used to fix and install the pipeline structure.

[0041] By setting the above structure, pipeline structures such as hydraulic pipes and lines can be fixedly installed along the length direction of the slide assembly 40 to prevent the pipeline structure from contacting the side wall of the main boom 10 or other protruding parts.

[0042] Based on this, when the first telescopic arm 20 extends the main boom 10 or retracts the main boom 10 in the length direction of the main boom 10, the first telescopic arm 20 drives the connected slide assembly 40 to move synchronously in the length direction of the slide rail portion 30, and makes the pipeline structure fixedly connected in the length direction of the slide assembly 40 move synchronously with the slide assembly 40. In this process, the slide assembly 40 can protect the fixedly connected pipeline structure and prevent the pipeline structure from bending and stretching in the process of reciprocating with the first telescopic arm 20, so as to reduce or avoid the pipeline from contacting, rubbing or hanging with other parts to cause the line to be damaged or broken, which is beneficial to improve the service life of the pipeline structure and increase the overall stability of the telescopic boom.

[0043] The main structure of the carriage assembly 40 may be a plate structure or a mesh structure, which has a good protective effect. The main structure of the carriage assembly 40 may also be a frame structure, which is used to fix the connection and stably support the pipeline structure.

[0044] In some embodiments, Figure 3 and Figure 4 As shown, the carriage assembly 40 includes a shield member 41, combined with Figure 1 and Figure 2 The shield member 41 is extended along the length direction of the main boom 10 , and a storage space for the pipeline structure is provided below the shield member 41 . One end of the shield member 41 is slidably connected to the slide rail portion 30 , and the other end of the shield member 41 is connected to the first telescopic arm 20 .

[0045] Since there is a storage space for the pipeline structure below the shield member 41, the shield member 41 can shield and protect the pipeline structure fixedly connected in the pipeline storage space, preventing the first telescopic arm 20 from driving the pipeline structure to contact or hook with other parts during the telescopic movement. On this basis, during the construction process, the shield member 41 can also prevent foreign objects such as stones falling from above from directly falling onto the pipeline structure, further increasing the protection effect of the pipeline structure.

[0046] In some embodiments, Figure 1 and Figure 3 As shown, the carriage assembly 40 further includes a sliding claw portion 42, and one end of the shield member 41 away from the first telescopic arm 20 is connected to the sliding claw portion 42, and the sliding claw portion 42 is slidably connected to the slide rail portion 30. Through the clamping adaptation of the sliding claw portion 42 and the slide rail portion 30, the shield member 41 can slide smoothly along the length direction of the slide rail portion 30, and the structure is simple.

[0047] For the adaptive combination between the slide rail portion 30 and the slide claw portion 42. Figure 1 and Figure 3 As shown, the slide rail portion 30 may be a long strip slide rail extending along the length direction of the main boom 10, and the corresponding sliding claw portion 42 is a claw member having a clamping groove opened toward the main boom 10. One end of the long strip slide rail may be plugged and matched with the clamping groove of the claw member along the length direction of the main boom 10, so that the clamping structure of the clamping groove and the slide rail prevents the sliding claw portion 42 from being separated from the slide rail portion 30, and the slide rail portion 30 may be slidably arranged along the length direction of the slide rail portion 30.

[0048] Alternatively, the slide rail portion 30 may also be a slide groove structure arranged along the length direction of the main boom 10, and the sliding claw portion 42 is a clamping joint with a protrusion, and is clamped and adapted to the slide groove structure, so that the sliding claw portion 42 can slide back and forth along the length direction of the slide rail portion 30 and prevent the two from being separated from each other.

[0049] It should be noted that in the above embodiment, the sliding claw portion 42 and the shield member 41 are two independent components. Alternatively, a claw structure may be provided at one end of the shield member 41 away from the first telescopic arm 20 without additionally providing the sliding claw portion 42 .

[0050] The end of the shield member 41 may directly contact the first telescopic arm 20 , and the two components may be connected by bolts, rivets, a clamping structure or welding.

[0051] Or, if Figure 1 and Figure 2 As shown, the pipeline installation structure 100 of the telescopic boom may also include a connecting member 43. One end of the connecting member 43 is fixedly connected to the shield member 41, and the other end of the connecting member 43 is fixedly connected to the first telescopic arm 20.

[0052] In some embodiments, Figure 3 and Figure 4 As shown, the shield member 41 also includes a fixing plate 411 and a shield plate 412. Along the length direction of the main boom 10, one end of the fixing plate 411 is slidably connected to the slide rail portion 30, and the other end of the fixing plate 411 is connected to the first telescopic arm 20 (such as Figure 1 The shield plate 412 is connected to a side of the fixing plate 411 away from the main boom 10, and a storage space for the pipeline structure is provided below the shield plate 412.

[0053] Exemplarily, one end of the fixing plate 411 may be connected to a first telescopic arm 20 via a connecting member 43 , and the other end of the fixing plate 411 may be slidably connected to the slide rail portion 30 via a sliding claw portion 42 .

[0054] By setting the lower part of the shield plate 412 as the installation and storage space of the pipeline structure, while the pipeline structure is connected and fixed, the shield plate 412 located above can effectively protect the lower pipeline structure to prevent foreign objects such as stones falling from above from directly hitting the pipeline structure. On this basis, the fixing plate 411 is connected to the side of the shield plate 412 close to the main boom 10, and is connected to the sliding claw part 42 and the first telescopic arm 20, while supporting the shield member 41. The fixing plate 411 is also set below the shield plate 412 to separate the pipeline structure from the main boom 10, and further prevent the pipeline structure from contacting and wearing with other parts on the main boom 10 or even breaking at the connection.

[0055] Exemplarily, the shield plate 412 extends along the length direction of the main boom 10, so that the shield plate 412 has a sufficient length to effectively protect the pipeline structure below over a large area. While ensuring the structural strength, strip holes or hollow structures can be opened on the fixing plate 411 to reduce the structural weight.

[0056] In addition, reinforcing ribs may be formed on the fixing plate 411 and the shield plate 412 by stamping, which is beneficial to improving the bending strength of the fixing plate 411 and the shield plate 412 .

[0057] In some embodiments, Figure 3 and Figure 4 As shown, the carriage assembly 40 further includes a carriage support 44. The carriage support 44 may be a long strip structure, a tubular structure, a rod structure, etc. The carriage support 44 extends along the length direction of the main boom 10 and is connected to the fixing plate 411 to improve the bending strength of the fixing plate 411 in the length direction of the main boom.

[0058] Exemplarily, the carriage support 44 can be installed on the side of the fixing plate 411 away from the main boom 10, or on the side of the fixing plate 411 close to the main boom 10. Alternatively, an additional carriage support 44 can be provided to connect with the shield plate 412 to improve the bending strength of the shield plate 412.

[0059] Taking the example that the carriage support member 44 is located between the fixed plate 411 and the main boom 10, one end of the carriage support member 44 can be fixedly connected to the sliding claw portion 42, and the other end of the carriage support member 44 can be connected to the first telescopic arm 20. The fixed plate 411 is connected to the carriage support member 44 at multiple fixed points arranged at intervals along its length direction, and the two components can be connected by bolts, rivets or welding.

[0060] In some embodiments, Figure 3 and Figure 4 As shown, the carriage assembly 40 also includes a plurality of pipe brackets 45, combined with Figure 1 and Figure 2 A plurality of pipeline supports 45 are distributed along the length direction of the main boom 10 and are connected to the shield member 41 .

[0061] By distributing a plurality of pipeline supports 45 along the length direction of the main boom 10 and connecting and setting the pipeline structures such as pipelines or lines can be fixedly connected to the plurality of pipeline supports 45 along the length direction of the main boom 10. While the pipeline structures are protected by the shield 41, the pipeline structures can reciprocate synchronously with the shield 41 along the length direction of the main boom 10 to reduce or avoid the situation that the pipelines are in contact with other parts, rubbed or hooked, and the lines are damaged or broken.

[0062] In some embodiments, Figure 3 and Figure 4As shown, the shield member 41 includes a fixing plate 411 and a shield plate 412, and the pipeline support 45 is located at the lower side of the shield plate 412. The pipeline support 45 includes a fixing section 451, a supporting section 452 and a protecting section 453. One end of the fixing section 451 close to the shield plate 412 is connected to the fixing plate 411. One end of the supporting section 452 is connected to one end of the fixing section 451 away from the shield plate 412, and the supporting section 452 and the shield plate 412 are located on the same side of the fixing plate 411. The protecting section 453 and the fixing section 451 are located on the same side of the supporting section 452, and one end of the protecting section 453 is connected to one end of the supporting section 452 away from the fixing section 451, so as to enclose a receiving groove with an opening facing the shield plate 412.

[0063] In this way, during the process of installing the pipeline structure between multiple pipeline supports 45, the pipeline can be first placed in the storage groove of each pipeline support 45 in turn, and then the pipeline can be tightened by structures such as straps or ropes to make it stably connected to the pipeline support 45, and the operation process is convenient and quick.

[0064] In some embodiments, Figure 3 and Figure 4 As shown, the carriage assembly 40 further includes a locking portion 46 , and at least a portion of the pipeline support 45 is provided with the locking portion 46 .

[0065] The locking portion 46 may be a structure such as a binding strap, a cable tie or a rope, etc., which is used to bundle a plurality of pipeline structures and stably connect them to the pipeline support 45 .

[0066] For example, continue to refer to Figure 4 The locking portion 46 includes a strap 461 and a ratchet mechanism 462. One end of the strap 461 is connected to the shield member 41 or the pipeline support 45. The other end of the strap 461 is connected to the ratchet mechanism 462, and the ratchet mechanism 462 is used to store the strap 461.

[0067] By cooperating with the binding belt 461 and the ratchet mechanism 462, the pipeline structure in the storage groove can be fastened conveniently and quickly, and stably connected to the pipeline support 45. The operation is convenient and labor-saving, and the setting of the ratchet mechanism 462 can avoid the shaking of the pipeline caused by the loosening of the binding belt, thereby avoiding the shaking and friction of multiple pipeline supports.

[0068] In some embodiments, Figure 3 and Figure 4 As shown, the carriage assembly 40 further includes at least one of a plurality of line supports 47 and a plurality of pipe clamps 48 .

[0069] Multiple line brackets 47 are distributed along the length direction of the main boom 10 and connected to the shield member 41. For example, the line bracket 47 is connected to the side of the fixing plate 411 away from the main boom 10, and multiple line brackets 47 are distributed at intervals along the length direction of the fixing plate 411, and one line bracket 47 is connected to the fixing plate 411 and forms a line groove opening toward the shield plate 412. Lines and other structures can be placed in the line grooves of the multiple line brackets 47 in sequence and fixedly connected to the line brackets 47 by a binding or tie structure.

[0070] A plurality of pipe clamps 48 are distributed along the length direction of the main boom 10 and connected to the shield member 41. The pipe clamps 48 are detachable storage structures. Exemplarily, the pipe clamps 48 can be installed on the lower side of the shield plate 412, or on the side of the fixed plate 411 away from the main boom 10. The pipe clamp 48 includes a first clamp seat and a second clamp seat. The first clamp seat is connected to the fixed plate 411 or the shield plate 412. The second clamp seat is detachably connected to the first clamp seat through a clamping structure or bolts, and a plurality of accommodating through holes are formed between the first clamp seat and the second clamp seat. The axis of the accommodating through hole is arranged parallel to the length direction of the main boom 10, and the plurality of accommodating through holes in a pipe clamp 48 are spaced apart in a direction perpendicular to the axis, so that the pipe clamp 48 can fix and install one or more pipelines.

[0071] In this way, in the slide assembly 40, by providing a variety of support structures such as the pipeline support 45, the line support 47 and the pipe clamp 48, different support structures can be selected for different pipeline structures for connection and installation, and the adaptability is high.

[0072] On the other hand, the utility model also provides a construction equipment, including a trolley and the pipeline installation structure 100 of the telescopic boom in the above aspect. Among them, the first telescopic arm 20 is plugged and arranged at one end of the main boom 10, and the other end of the main boom 10 is movably connected to the trolley.

[0073] In this way, by setting up the trolley, while stably supporting the main boom 10, the trolley can flexibly adjust the pitch angle and telescopic length of the telescopic boom through hydraulic transmission or other transmission structures. In addition, while providing adjustment power for the telescopic operation of the telescopic boom, the trolley can also drive the pipeline installation structure 100 of the telescopic boom to move.

[0074] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
