Description

Technical Field

[0001] The invention relates to the field of aerial work platforms, and in particular to a pressure rod for a self-propelled aerial platform and a processing method thereof. Background Art

[0002] The self-propelled aerial platform includes two sets of anti-tilt pothole protection devices, which are placed on both sides of the platform. The automatic operation of the anti-tilt pothole protection devices is achieved by the scissors of the platform descending or rising to compress and release the pressure rod.

[0003] like Figure 1 The pressure rod shown includes a rod sleeve 1, a plug 2, a rod body 5 and a compression spring 4. An inner stopper is arranged at the front end of the rod sleeve 1, and the inner stopper is used to limit the rod body 5 from moving out of the rod sleeve 1. When the press assembly is performed, the rod body 5 is first inserted from the rear end of the rod sleeve 1, and then the compression spring is installed, and finally the plug is welded on the rear end of the rod sleeve 1. After the plug is welded, the outer wall of the rod sleeve 1 and the plug are turned to unify the outer diameter of the pressure rod. The pressure rod after turning is finally subjected to surface treatment, and is pickled and galvanized in sequence. Since the pressure rod is limited by its own structure, during the pickling process, galvanized hydrochloric acid easily enters the rod sleeve 1 from between the inner stopper and the rod body 5, and the galvanized hydrochloric acid is difficult to discharge, thereby affecting the quality of the entire pressure rod. Summary of the invention

[0004] The technical problem to be solved by the present invention is: to overcome the shortcomings of the prior art, to provide a pressure rod for a self-propelled aerial platform and a processing method thereof, to solve the technical problem that the unreasonable structural design of the traditional pressure rod causes the pickling liquid to easily enter the interior of the pressure rod during the later pickling process, thereby affecting the overall quality of the pressure rod.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] First aspect:

[0007] A pressure rod for a self-propelled aerial platform is provided, comprising:

[0008] A rod sleeve, a plug is arranged at the rear end of the rod sleeve, a compression spring is arranged inside the rod sleeve, and a guide sleeve is pressed and arranged at the front end of the rod sleeve;

[0009] The rod body comprises a large-diameter rod and a small-diameter rod, the large-diameter rod is slidably matched with the inner cavity of the rod sleeve, the compression spring is located between the plug and the large-diameter rod, and the small-diameter rod extends from the guide sleeve and is slidably matched with the guide sleeve;

[0010] The inner wall of the rod sleeve is provided with a circle of first slots, the first slots are located at the rear side of the guide sleeve, and the outer wall of the small-diameter rod is provided with a circle of second slots;

[0011] The retaining spring is suitable for radial elastic deformation. When the retaining spring is radially pressed into the second slot, the small-diameter rod is suitable for moving in the rod sleeve with the retaining spring. When the retaining spring moves to the first slot, the retaining spring is radially reset and enters the first slot. At this time, the retaining spring is suitable for abutting against the front end of the large-diameter rod, thereby limiting the rod body from moving out of the rod sleeve.

[0012] Furthermore, a radial limiting platform is provided at the front end of the large diameter rod, and the outer diameter of the radial limiting platform is larger than that of the small diameter rod and smaller than that of the large diameter rod;

[0013] When the front end of the large diameter rod abuts against the retaining spring, the radial limiting platform is located in the retaining spring and is suitable for limiting the radial contraction and deformation of the retaining spring.

[0014] Furthermore, a guiding inclined surface is provided at the front end of the radial limiting platform, and the guiding inclined surface abuts against the retaining spring, thereby guiding the radial limiting platform to enter the retaining spring.

[0015] Furthermore, the front end surface of the radial limiting platform is connected to the second clamping groove.

[0016] Furthermore, a positioning platform is provided at the rear end of the rod body, and the positioning platform is inserted from the front end of the compression spring.

[0017] Second aspect:

[0018] A method for processing a pressure rod is provided, using the pressure rod, comprising the following steps:

[0019] Step S1, welding the plug to the rear side of the rod sleeve, then turning the outer surfaces of the rod sleeve and the plug to unify the outer diameters, and then performing pickling and galvanizing treatment;

[0020] Similarly, the processed rod body is directly pickled and galvanized;

[0021] After all parts are pickled, galvanized and air-dried, they enter the assembly stage;

[0022] Step S2, install the compression spring from the front end of the rod sleeve, insert the large diameter rod into the rod sleeve first, press the retaining spring into the second slot of the small diameter rod, then the small diameter rod enters the rod sleeve together, the rod body drives the retaining spring to move backward in the rod sleeve to the first retaining spring, then the retaining spring is radially reset and enters the first slot, and the retaining spring is installed;

[0023] Step S3, press-fitting the guide sleeve at the front end of the rod sleeve.

[0024] The beneficial effects of the present invention are:

[0025] The newly designed pressure rod can be pickled and galvanized for each part before assembly. The assembled pressure rod will no longer have zinc-plated hydrochloric acid inside, making the quality of the entire pressure rod more stable and reliable.

[0026] The installation structure of the retaining spring at the front end of the rod sleeve enables the rod body to be assembled by directly inserting it from the front end of the rod sleeve, changing the traditional rear insertion assembly to the current front insertion assembly. The retaining spring has a stable structure in the rod sleeve and is not easy to loosen. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The present application provides a pressure rod for a self-propelled aerial platform, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0043] In order to solve the technical problem that the unreasonable design of the pressure rod structure in the prior art causes the pickling liquid to easily enter the interior of the pressure rod during the later pickling process, thereby affecting the overall quality of the pressure rod, an embodiment of the present application provides a pressure rod for a self-propelled aerial platform. The following is a detailed description.

[0044] like Figures 1 to 5 As shown, a pressure rod for a self-propelled aerial platform includes

[0045] A rod sleeve 1, a plug 2 is arranged at the rear end of the rod sleeve 1, a compression spring 3 is arranged inside the rod sleeve 1, and a guide sleeve 4 is press-fitted at the front end of the rod sleeve 1;

[0046] The rod body 5 includes a large-diameter rod 51 and a small-diameter rod 52. The large-diameter rod 51 is slidably matched with the inner cavity of the rod sleeve 1. The compression spring 3 is located between the plug 2 and the large-diameter rod 51. The small-diameter rod 52 extends from the guide sleeve 4 and is slidably matched with the guide sleeve 4.

[0047] The inner wall of the rod sleeve 1 is provided with a circle of first slots 61, the first slots 61 are located at the rear side of the guide sleeve 4, and the outer wall of the small-diameter rod 52 is provided with a circle of second slots 62;

[0048] The retaining spring 7 is suitable for radial elastic deformation. When the retaining spring 7 is radially pressed into the second slot 62, the small-diameter rod 52 is suitable for moving in the rod sleeve 1 with the retaining spring 7. When the retaining spring 7 moves to the first slot 61, the retaining spring 7 is radially reset and enters the first slot 61. At this time, the retaining spring 7 is suitable for abutting against the front end of the large-diameter rod 51, thereby limiting the rod body 5 from moving out of the rod sleeve 1.

[0049] Specifically, as an optional implementation in this embodiment, Figures 2 to 5 As shown, a radial limiting platform 53 is provided at the front end of the large diameter rod 51, and the outer diameter of the radial limiting platform 53 is larger than the small diameter rod 52 and smaller than the large diameter rod 51;

[0050] When the front end of the large diameter rod 51 abuts against the retaining spring 7, the radial limiting platform 53 is located in the retaining spring 7 and is suitable for limiting the radial contraction and deformation of the retaining spring 7.

[0051] In this embodiment, the clamping spring 7 is a C-shaped clamping spring 7, which is an existing product.

[0052] In this embodiment, the radial limiting platform 53, the large diameter rod 51 and the small diameter rod 52 are all integrated structures.

[0053] Specifically, as an optional implementation in this embodiment, Figures 2 to 5 As shown, a guiding inclined surface 54 is provided at the front end of the radial limiting platform 53 , and the guiding inclined surface 54 abuts against the retaining spring 7 , thereby guiding the radial limiting platform 53 to enter the retaining spring 7 .

[0054] The guiding bevel 54 forms a conical surface at the front end of the radial limit platform 53. Each time the rod body 5 moves forward, the radial limit platform 53 must be inserted into the retaining spring 7 before the large diameter rod 51 contacts the retaining spring 7. The guiding bevel 54 allows the radial limit platform 53 to smoothly enter the retaining spring 7. The radial limit platform 53 in the retaining spring 7 can limit the radial contraction of the retaining spring 7, so that the retaining spring 7 can only be limited in the first groove 61. The retaining spring 7 abuts against the front end of the large diameter rod 51 to limit the position of the entire rod body 5 in the rod sleeve 1.

[0055] Specifically, as an optional implementation in this embodiment, Figure 5 As shown, the front end surface of the radial limiting platform 53 is connected to the second clamping groove 62. This structure is mainly for facilitating the processing of the entire rod body 5.

[0056] Specifically, as an optional implementation in this embodiment, Figures 2 to 5 As shown, a positioning platform 55 is provided at the rear end of the rod body 5 , and the positioning platform 55 is inserted from the front end of the compression spring 3 .

[0057] In the compression rod of the present invention, through the newly involved mounting structure of the retaining spring 7, the rod body 5 can be directly inserted from the front end of the rod sleeve 1 for assembly, and the performance of the compression rod is stable and reliable.

[0058] like Figure 6 and Figure 7 As shown, the self-propelled aerial platform is equipped with two sets of anti-tilt pothole protection devices 8, and the rod body 5 is a part of the anti-tilt pothole protection device 8. The rod body 5 of the pressure rod cooperates with the cylinder support plate in the self-propelled aerial platform. After the platform descends, the cylinder support plate abuts against the pressure rod, thereby retracting the support plate 81, lifting the platform, separating the cylinder bracket from the pressure rod, and then opening the support plate 81 to support the ground.

[0059] like Figures 2 to 4 As shown, a method for processing a pressure rod, using the above-mentioned pressure rod, comprises the following steps:

[0060] Step S1, welding the plug 2 to the rear side of the rod sleeve 1, then turning the outer surfaces of the rod sleeve 1 and the plug 2 to unify the outer diameters, and then performing pickling and galvanizing treatment;

[0061] Similarly, the processed rod body 5 is also directly pickled and galvanized;

[0062] After all parts are pickled, galvanized and air-dried, they enter the assembly stage;

[0063] Step S2, the compression spring 3 is installed from the front end of the rod sleeve 1, the large diameter rod 51 is inserted into the rod sleeve 1 first, the retaining spring 7 is pressed into the second clamping groove 62 of the small diameter rod 52, and then the small diameter rod 52 enters the rod sleeve 1 together, and the rod body 5 drives the retaining spring 7 to move backward in the rod sleeve 1 to the first retaining spring 7, and then the retaining spring 7 is radially reset and enters the first clamping groove 61, and the retaining spring 7 is installed;

[0064] Step S3, press-fitting the guide sleeve 4 at the front end of the rod sleeve 1.

[0065] The newly designed pressure rod can be pickled and galvanized for each part before assembly. The assembled pressure rod will no longer have zinc-plated hydrochloric acid inside, making the quality of the entire pressure rod more stable and reliable.
