DETAILED DESCRIPTION

[0024] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0025] As shown in Figure 1 , Figure 2 A tower platform and railing connection detection tool, comprising: a guide rail 10, the guide rail 10 is straight bar shape; A plurality of platform connecting sleeve detection heads 20, a plurality of platform detection heads are sequentially installed on the first side of the guide rail 10 along the length direction of the guide rail 10; A plurality of platform connecting sleeve detection heads 20 are used for inserting into the corresponding platform connecting sleeve 30 during detection; A plurality of railing detection heads 40, a plurality of railing detection heads 40 are sequentially installed on the second side of the guide rail 10 along the length direction of the guide rail 10; A plurality of railing detection heads 40 are used for sleeving on the corresponding railing leg 50 during detection;

[0026] The positions of the plurality of platform connecting sleeve detection heads 20 are determined according to the design positions of the plurality of platform connecting sleeves 30; the positions of the plurality of railing detection heads 40 are determined according to the design positions of the plurality of railing legs 50.

[0027] Specifically, the guide rail 10 is a straight bar structure made of aluminum alloy, which is used to support and guide the movement of the platform connecting sleeve detection heads 20 and the railing detection heads 40. The design of the guide rail allows the detection heads to slide in the length direction to adapt to different detection requirements.

[0028] The plurality of platform connecting sleeve detection heads 20 are sequentially installed on the first side of the guide rail 10 along the length direction of the guide rail 10. The plurality of platform connecting sleeve detection heads 20 are used to be inserted into the corresponding platform connecting sleeves 30 during the detection process. The position of each platform connecting sleeve detection head 20 includes the distance between adjacent platform connecting sleeve detection heads 20, which is determined according to the design size of the platform connecting sleeves 30 on the drawing. When setting the plurality of platform connecting sleeve detection heads 20, the position of the first platform connecting sleeve detection head 20 at the outermost side is determined first, and then the positions of the second and third platform connecting sleeve detection heads 20 adjacent to the first platform connecting sleeve detection head 20 are determined using a tape measure according to the size on the drawing. If there are three railing legs 50, the position of the third platform connecting sleeve detection head 20 is determined in the same way. After the positions of the platform connecting sleeve detection heads 20 are determined, each platform connecting sleeve detection head 20 is matched with each platform connecting sleeve 30. If the plurality of platform connecting sleeve detection heads 20 can be inserted into the corresponding platform connecting sleeves 30 simultaneously, it means that the platform connecting sleeves 30 are qualified. After the positions of the plurality of platform connecting sleeve detection heads 20 are determined according to the size on the drawing, the dimensions of the railing legs 50 of the handrail can be detected in batches.

[0029] The plurality of railing detection heads 40 are sequentially installed on the second side of the guide rail along the length direction of the guide rail 10. The railing detection heads 40 are sleeved on the corresponding railing legs 50 during the detection process. The position of each railing detection head 40 is determined according to the design size of the railing legs on the drawing, which ensures that the dimensions and positions of the railing legs 50 can be accurately detected. The determination process of the positions of the plurality of railing detection heads 40 refers to the determination process of the plurality of platform connecting sleeve detection heads 20. In addition, the first platform connecting sleeve detection head 20 is located at the first end of the guide rail 10, and the first railing detection head 40 is located at the second end of the guide rail 10.

[0030] The detection efficiency can be improved by using the detection tool, and the complexity and time cost of manual operation can be reduced. The traditional detection method requires multiple people to cooperate, and the efficiency is low. Using the detection tool of the present application, one person can complete the detection work, greatly improving the production efficiency and reducing the production cost. Moreover, the positions of the platform connecting sleeve detection head 20 and the railing detection head 40 in the length direction of the guide rail 10 can be adjusted, and the platform connecting sleeve detection head 20 and the railing detection head 40 can be replaced according to different models, so that the detection tool can adapt to the detection needs of tower platform and railing of different models. In addition, by using such a detection tool in the production stage, unqualified platforms and railings can be found in time to avoid sending unqualified products to the site. Reduce errors during on-site installation, avoid the trouble of needing to modify the installation position due to installation failure, and improve the reputation and market competitiveness of the enterprise.

[0031] The detection tool in the present application can be disassembled according to different tasks, and the platform connecting sleeve detection head 20 can be used for handrail detection, or the railing detection head 40 can be used for platform connecting sleeve 30 detection.

[0032] In one possible implementation, the guide rail 10 includes: a first side plate 11; two second side plates 12, the two second side plates 12 are opposite, and the first ends of the two second side plates 12 are connected to the two sides of the first side plate 11 respectively; two third side plates 13, the first ends of the two third side plates 13 are opposite and have a spacing, and the second ends of the two third side plates 13 are connected to the second ends of the two second side plates 12 respectively; wherein the first side plate 11, the two second side plates 12 and the two third side plates 13 form a containing space; the two third side plates 13 and the spacing are used for installing the platform connecting sleeve detection head 20 and the railing detection head.

[0033] Specifically, as shown in Figure 3 The first side plate 11 serves as a basic support part to provide stability for the entire guide rail 10; the two second side plates 12 are arranged opposite to each other, and the first ends of the two second side plates 12 are connected to the two sides of the first side plate 11, together with the second side plates to build the basic frame profile of the guide rail; the first ends of the two third side plates 13 are opposite and have a spacing, and the second ends are connected to the second ends of the two second side plates 12 respectively, so that the first side plate 11, the two second side plates 12 and the two third side plates 13 form a containing space, and the two third side plates 13 and the spacing therebetween can be used for installing the platform connecting sleeve detection head 20 and the railing detection head 40. This structural design enables the guide rail 10 to have stable support performance while reasonably arranging the detection heads to meet the corresponding detection needs.

[0034] In one possible implementation, the platform connecting sleeve detection head 20 includes: a first connecting structure 21, the first end of which is detachably mounted on the guide rail 10; a first sleeve 22, which is a hollow cylinder, the outer surface of the first end of which is connected to the second end of the first connecting structure 21; the first sleeve 22 is located on the first side of the guide rail 10; wherein, the second end of the first sleeve 22 has a first through hole perpendicularly penetrating its central axis; the axis of the first through hole is perpendicular to the length direction of the guide rail 10; when detecting the platform connecting sleeve 30, the first sleeve 22 is nested inside the platform connecting sleeve 30, and the first through hole is not blocked by the platform connecting sleeve 30.

[0035] Specifically, such as Figure 4 As shown, the first end of the first connecting structure 21 can be detachably mounted on the guide rail 10, facilitating the installation and removal of the platform connecting sleeve detection head 20 and allowing for adjustment or replacement of the platform connecting sleeve detection head 20 according to actual testing needs. The first sleeve 22 is a hollow cylinder, with its first end outer surface connected to the second end of the first connecting structure 21 and located on the first side of the guide rail 10, enabling the detection head to be positioned and moved based on the guide rail 10. The second end of the first sleeve 22 has a first through hole perpendicularly through its central axis, the axis of which is perpendicular to the length direction of the guide rail 10. During the testing process, the first sleeve 22 can be nested into the platform connecting sleeve 30. When the railing leg 50 is normally installed in the corresponding platform connecting sleeve 30, the bottom end of the railing leg 50 extends out of the platform connecting sleeve 30 by a small section, and the extended part has a first through hole perpendicular to the central axis of the railing leg 50. This first through hole is used to insert a cotter pin to prevent the railing leg 50 from coming out of the corresponding platform connecting sleeve 30. The first sleeve 22 is nested inside the platform connecting sleeve 30, and the first through hole is not blocked by the platform connecting sleeve 30. This allows for further detection of the length of the platform connecting sleeve 30, preventing the platform connecting sleeve 30 from being too long and blocking the first through hole at the bottom of the railing leg 50 when it is inserted, thus preventing the cotter pin from being inserted normally.

[0036] In a possible implementation, the first end of the first side plate 11 is marked with a first scale line, and the first connecting structure 21 comprises: a first positioning plate 211, which is marked with a first center line that is perpendicular to the first scale line; a first fixed plate 212, a first end of which is connected to the first positioning plate 211; a second end of the first fixed plate 212 is connected to the first sleeve 22; a first fixing assembly 213, which is used to fix the first fixed plate 212 to the third side plate 13; and a first connecting plate 214, which is perpendicular to the central axis of the first sleeve 22, a first end of the first connecting plate 214 is connected to the second end of the first fixed plate 212, and a second end of the first connecting plate 214 is connected to the outer surface of the first end of the first sleeve 22; when the first positioning plate 211 is located at the first end of the first side plate 11, the first center line is aligned with the first scale line.

[0037] Specifically, the first connecting structure 21 comprises the first positioning plate 211, which is marked with the first center line that is perpendicular to the first scale line, ensuring accurate positioning. The first fixed plate 212 connects the first positioning plate 211 and the first sleeve 22, and is fixed to the third side plate 13 through the first fixing assembly 213. The first connecting plate 214 is perpendicular to the central axis of the first sleeve 22, and connects the first fixed plate 212 and the first sleeve 22, ensuring the stability of the overall structure. In the installed state, the first positioning plate 211 is attached to one of the second side plates 12.

[0038] When the first positioning plate 211 is located at the first end of the first side plate 11, i.e., the platform connecting sleeve detection head 20 on which the first positioning plate 211 is located is the first platform connecting sleeve detection head 20 with a determined position, by aligning the first center line of the first platform connecting sleeve detection head 20 with a determined position with the first scale line, a zero point of the detection tool when detecting the platform connecting sleeve 30 is formed, accurate positioning of the platform connecting sleeve detection head 20 is achieved, and the accuracy and consistency of detection are ensured.

[0039] In a possible implementation, the first fixing plate 212 is provided with a second through hole, and the first fixing assembly 213 includes: a first bolt 2131 passing through the second through hole and the spacer; a first end of the first bolt 2131 is located in the accommodation space; a second end of the first bolt 2131 is located on a side of the first fixing plate 212 away from the third side plate 13; a first screw head 2132 is arranged at the second end of the first bolt 2131; and a first nut 2133 is located in the accommodation space and is screwed to the first end of the first bolt 2131; wherein the first screw head 2132 and the first nut 2133 cooperate to lock the first fixing plate 212 and the two third side plates 13.

[0040] Specifically, in the detection tool, the first fixing plate 212 is provided with a second through hole for cooperation with the first fixing assembly 213 to achieve fixation. The first fixing assembly 213 includes a first bolt 2131, a first screw head 2132, and a first nut 2133. The first bolt 2131 passes through the second through hole and extends into the accommodation space. A first end of the first bolt is located in the accommodation space, and a second end is located on a side of the first fixing plate 212 away from the third side plate 13. The first screw head 2132 is arranged at the second end of the first bolt for manually rotating the bolt. The first nut 2133 is located in the accommodation space and is screwed to the first end of the first bolt.

[0041] During installation, the square edge of the first nut matches the square boundary of the accommodation space, ensuring the stability and correct position of the nut in the space. By rotating the first screw head, the first fixing plate 212 and the two third side plates 13 are locked, achieving fixation of the detection head.

[0045] Specifically, in the detection tool, the second end of the first side plate 11 is marked with a second scale line for accurately positioning the initial measurement point. The second connecting structure 41 includes a second positioning plate 411, and a second center line on the second positioning plate 411 is perpendicular to the second scale line, ensuring the accurate position of the railing detection head 40. The second fixing plate 412 connects the second positioning plate 411 and the second sleeve 42, and is fixed with the third side plate 13 through the second fixing assembly 413. The second connecting plate 414 is perpendicular to the central axis of the second sleeve 42, and connects the second fixing plate 412 and the second sleeve 42, ensuring the stability of the overall structure. In the installed state, the second positioning plate 411 is attached to the other second side plate 12. When the second positioning plate 411 is located at the second end of the first side plate 11, that is, the railing detection head 40 where the second positioning plate 411 is located is the first determined position of the railing detection head 40, by aligning the first center line of the first determined position of the railing detection head 40 with the second scale line, the zero point of the detection tool when detecting the railing is formed, realizing the accurate positioning of the railing detection head 40 and ensuring the accuracy and consistency of the detection.

[0047] Specifically, the second fixing assembly 413 is used to lock the second fixing plate 412 and the third side plate 13 of the guide rail 10. Specifically, a third through hole is formed in the second fixing plate 412, and the second bolt 4131 passes through the third through hole and extends into the accommodation space. The first end of the second bolt 4131 is located in the accommodation space, and the second end is located on the side of the second fixing plate 412 away from the third side plate 13.

[0049] In a possible implementation, the end face of the second end of the first sleeve 22 is chamfered.

[0050] Specifically, chamfering can prevent the sharp edge of the first sleeve 22 from damaging the platform connecting sleeve 30 when the first sleeve 22 is nested in the platform connecting sleeve 30. Similarly, the second end of the second sleeve 42 is also chamfered to prevent scratches on the railing leg 50 when the railing leg 50 is nested in the second sleeve 42.

[0051] In general, the detection tool of the present application adopts a linear guide rail 10, which can realize the sliding of the platform connecting sleeve detection head 20 and the railing detection head 40 on the guide rail 10, and is convenient to replace. Compared with the fixed detection in the past, it is more flexible, and by using a tape measure to calibrate according to the drawing size, the connection of the platform and the railing of different types of tower cranes can be detected. In addition, different detection heads can be replaced to realize the timely detection of the railing leg 50 and the platform connecting sleeve 30, playing the role of two detections without the need to additionally increase detection devices. Moreover, originally when detecting the platform and the railing, the workshop team needs to send 4 people, including: a crane, a crane driver, a technician, an inspector, two people from the team to pull the ruler and make records, etc., which has low production efficiency and high error rate. Using the detection tool of the present application, only one person is needed to complete the detection work of the three parts of the tower crane, including the balance arm, the cab, the platform and the railing of the upper and lower layers of the sleeve frame, which significantly improves the economic benefit.

[0052] In addition, with the reduction of the error rate of the installation of the platform and the railing of the tower crane on site and the improvement of the one-time installation rate of the tower crane on site, the reputation of the tower crane manufacturing enterprise is also greatly improved.

[0053] The detection tool in the present application adopts aluminum alloy as the detection main body, which is light in weight, and the detection head part is made of steel material, so that one person can directly hold the detection tool without the assistance of others, achieving convenient and fast detection.

[0054] As can be seen from the above, the detection tool in the present application can completely solve the problem that has not been solved for a long time in actual work, and this tower crane platform and railing detection tool is necessary in actual production work.

[0055] The above merely is preferred embodiment of the present utility model, and is not used for limiting the present utility model, for the person skilled in the art, the present utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the present utility model should be contained in the protection scope of the present utility model.
