Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a beam hoisting tool. Background Art

[0002] During the assembly process of the three-dimensional coordinate measuring machine, for example, the triangular beam needs to be rotated a certain angle in the direction perpendicular to the triangular surface. However, the beam is generally made of marble. Due to its heavy weight, the triangular beam will be in a stable equilibrium state when placed horizontally.

[0003] Therefore, when assembling the triangular beam onto the three-coordinate measuring machine, it is necessary to use a crane and manpower to move and flip it before it can be installed on the three-coordinate machine. This process is time-consuming and labor-intensive, and is also prone to safety accidents.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a beam lifting tool, through which the beam lifting tool can ensure that the beam is rotated to the required angle after being lifted and stabilized, thereby reducing the manpower input during assembly and reducing the risk of accidents.

[0020] The sleeve comprises a cylindrical portion and a second annular protrusion annularly arranged at a second end portion of the cylindrical portion close to the flange surface;

[0021] The end surface of the second annular protrusion is flush with the end surface of the second end portion, and the first limiting hole is provided on the cylindrical portion;

[0022] When the shaft sleeve is sleeved on the shaft segment, the second annular protrusion abuts against the first annular protrusion.

[0023] In some embodiments of the present application, the force applying part includes:

[0024] an end cover fixed to an end surface of the first end portion of the shaft segment and having an annular surface with opposite end holes formed thereon;

[0039] Compared with the prior art, the beam hoisting tool provided by the present application has the following advantages and beneficial effects:

[0040] (1) By setting up assembly parts on the left and right sides of the beam, the beam can be hoisted using the hoisting part, eliminating the need for manual installation and transportation, thus saving manpower and time;

[0041] (2) During the hoisting process, if the beam needs to be rotated by a certain angle, an external rotational force is applied to the application part, and the rotational force is transmitted to the flange shaft. Since the sleeve is connected to the hoisting part and can rotate relative to the flange shaft, the rotational force can cause the flange shaft, the mounting seat and the beam to rotate, while the sleeve and the hoisting part are fixed and do not rotate. When the beam is rotated to the required angle, the limiting part passes through the first limiting hole on the hoisting part, the second limiting hole on the sleeve and the third limiting hole on the shaft section to lock the beam. At this time, the beam can no longer move, and thus the angle rotation of the beam is completed;

[0042] This angle rotation method does not require manpower to directly flip the beam, and only requires one person to use the force-applying part to complete the rotation, saving manpower and at the same time reducing the safety hazards caused by direct manpower flipping the beam;

[0043] (3) The force-applying part is arranged at one end of the beam in the length direction, avoiding the accident risk zone under the beam and improving the safety index.

[0044] After reading the specific embodiments of the present invention in conjunction with the accompanying drawings, other features and advantages of the present invention will become more clear. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] In order to reduce the manpower and safety risks required for carrying and flipping a triangular beam when it is assembled on a three-dimensional coordinate measuring machine, the present application relates to a beam lifting tool, which can easily realize the lifting and flipping of the beam and improve the safety factor at the same time.

[0063] See also Figures 1 to 10 The beam lifting tool includes two assembly parts, a force applying part 200 and a limiting part 300.

[0064] The two assembly parts are respectively denoted as a first assembly part 100 and a second assembly part 100 ′, wherein the first assembly part 100 is assembled to the left end of the beam 400 along its length direction, and the second assembly part 100 ′ is assembled to the right end of the beam 400 along its length direction.

[0065] The structures of the first fitting portion 100 and the second fitting portion 100 ′ are the same.

[0066] As follows, the structure of the first assembly portion 100 is taken as an example for description.

[0067] See also Figures 3 to 7 The first assembly part 100 includes a mounting seat 110 , a flange shaft 120 , a sleeve 130 and a hoisting part 140 .

[0068] The hoisting portion 140 of the first assembly portion 100 and the hoisting portion 140 ′ of the second assembly portion 100 ′ are used to hoist the beam 400 . During hoisting, a hoisting belt of an external machine (such as a crane) connects and fixes the hoisting portions 140 and 140 ′ on the left and right sides to fix the hoisted beam 400 .

[0069] The design of the structures of the hoisting parts 140 and 140 ′ should be aimed at stably hoisting the cross beam 400 , which will be described in detail below.

[0070] See also Figure 3 , Fig. 9 and Fig.10 The flange surface 122 of the flange shaft 120 is fixedly connected to the mounting seat 110, and both are fixedly connected to the left end surface of the left end portion of the beam 400. For example, when the beam 400 is a triangular beam, the cross-sectional shape of the beam 400 along the direction perpendicular to its length is a triangle.

[0071] In some embodiments of the present application, see Figure 4 The flange shaft 120 includes a flange surface 122 and a shaft section 121 , and a plurality of flange holes (not marked) are provided on the flange surface 122 .

[0072] See also Figure 3 The mounting seat 110 can be configured as a mounting plate, and a plurality of second mounting holes 112 are provided at positions corresponding to the plurality of flange holes.

[0073] The screws pass through the flange hole and the second mounting hole 112 to mount the flange shaft 120 onto the mounting seat 110 .

[0074] In some embodiments of the present application, in order to achieve better positioning and installation, see Figure 3 A through portion 111 is also provided on the mounting plate, which penetrates the mounting plate in the thickness direction, and a plurality of second mounting holes 112 as described above are provided around the through portion 111 .

[0075] See also Figure 4 The end face of the second end of the flange shaft 120 close to the flange surface 122 extends through the flange surface 122. When the multiple flange holes on the flange surface 122 are docked and installed with the multiple second mounting holes 112 respectively, the second end of the shaft section 121 extends into the through portion 111 for positioning.

[0076] In order to install the flange shaft 120 and the mounting plate onto the left end surface of the left end portion of the cross beam 400, a through hole 125 is formed inside the shaft section 121 for the first screw to pass through (see Fig.10 ), a first screw passes through the through hole 125 and through the through portion 111 to be installed on the end surface of the left end portion of the beam 400.

[0077] In addition, a first mounting hole (not marked) is provided on the mounting plate, which is fixed to the left end surface of the left end portion of the crossbeam 400 by a second screw.

[0078] In some embodiments of the present application, refer back to Figure 3 The shaft sleeve 130 is sleeved on the shaft segment 121 and is rotatable relative to the shaft segment 121 .

[0079] See also Figure 4The flange shaft 120 further includes a first annular protrusion 123 , which is arranged on the shaft segment 121 and is located on the side of the flange surface 122 facing the first end of the shaft segment 121 .

[0080] The first annular protrusion 123 is arranged close to the flange surface 122, and the radius of the circle where the first annular protrusion 123 is located is smaller than the radius of a circle formed by the multiple flange holes. In this way, the first annular protrusion 123 is prevented from affecting the connection between the multiple flange holes and the multiple second mounting holes 112 of the mounting plate.

[0081] See also Fig.10 The radius of the circle where the first annular protrusion 123 is located is greater than the inner diameter of the sleeve 130 . Therefore, when the sleeve 130 is sleeved on the shaft segment 121 , the second end of the sleeve 130 close to the flange surface 122 abuts against the first annular protrusion 123 to limit the right side of the sleeve 130 .

[0082] In some embodiments of the present application, see Figure 3 and Fig.10 The sleeve 130 may include a cylindrical portion 132 and a second annular protrusion 131 disposed at a second end portion of the cylindrical portion 132 close to the flange surface 122 .

[0083] The end surface of the second annular protrusion 131 is flush with the end surface of the second end portion, and see Fig.10 The radius of the circle where the second annular protrusion 131 is located is greater than the radius of the circle where the first annular protrusion 123 is located. In this way, when the sleeve 130 is sleeved on the shaft section 121, the second annular protrusion 131 abuts against the first annular protrusion 123 to achieve right side limiting of the sleeve 130.

[0084] To facilitate the turning of the crossbeam 400, see Figure 1 and Figure 3 The sleeve 130 passes through the through hole 1411 on the lifting part 140 and extends out. In some embodiments of the present application, the through hole 1411 is located in the middle of the lifting part 140 to ensure the lifting balance.

[0085] For aesthetic considerations, the end surface of the first end of the sleeve 130 extending out of the hanging portion 140 is flush with the end surface of the first end of the shaft segment 121 of the inner flange shaft 120 .

[0086] In some embodiments of the present application, see Figure 3 , Figure 6 and Figure 7 The hanging part 140 may include a square steel pipe 141 and a hanging ring part.

[0087] See also Figure 1 The length direction of the square steel tube 141 is perpendicular to the length direction of the cross beam 400 , the through hole 1411 is opened on the square steel tube 141 , and the axial direction of the through hole 1411 is perpendicular to the length direction of the square steel tube 141 .

[0088] The lifting ring is welded to the square steel pipe 141 for connection with the lifting belt of the lifting machine.

[0089] In some embodiments of the present application, in order to ensure the balance of the crossbeam 400 during lifting, the number of the lifting rings is set to two, which are respectively located at the two ends of the square steel tube 141.

[0090] The hanging part 140 may include a first hanging ring connecting column 142 , a second hanging ring connecting column 143 , a first hanging ring 144 and a second hanging ring 145 .

[0091] Holes are respectively opened at both ends of the square steel tube 141 in a direction perpendicular to the length direction thereof, and the first lifting ring connecting column 142 and the second lifting ring connecting column 143 are respectively passed through the corresponding holes and welded in the corresponding holes.

[0092] The top of the first lifting ring connecting column 142 has a first internal threaded hole (not marked), and the top of the second lifting ring connecting column 143 has a second internal threaded hole (not marked).

[0093] The first hanging ring 144 has a first ring portion (not marked) and a first connecting column (not marked) located on the first ring portion. The first connecting column has an external thread that is threadedly connected to the first internal threaded hole.

[0094] The second lifting ring 145 has a second ring portion (not marked) and a second connecting column (not marked) located on the second ring portion. The second connecting column has an external thread that is threadedly connected to the second internal threaded hole, thereby achieving the arrangement of the lifting portion 140.

[0095] In some embodiments of the present application, the crossbeam 400 can be rotated as long as any one of the left end and the right end of the crossbeam 400 is rotated. Therefore, a force applying portion 200 and a limiting portion 300 are provided for any assembly portion.

[0096] The structures of the force applying portion 200 and the position limiting portion 300 are described by taking the first mounting portion 100 as an example.

[0097] See also Figure 1 , Fig. 9 and Fig.10 The end surface of the first end portion of the shaft segment 121 in the flange shaft 120 in the first assembly portion 100 is fixedly connected to the force applying portion 200 .

[0098] In this way, the hoisting part 140 and the sleeve 130 are formed as one body, the force-applying part 200, the flange shaft 120, the mounting seat 110 and the cross beam 400 are formed as one body, and the sleeve 130 is sleeved on the flange shaft 120. Therefore, when rotational force is applied to the outside of the force-applying part 200, the flange shaft 120, the mounting seat 110 and the cross beam 400 will be driven to rotate together, while the hoisting part 140 and the sleeve 130 are fixed due to the hoisting. In this way, while ensuring that the cross beam 400 is stably hoisted, the angle rotation of the cross beam 400 can be achieved.

[0099] In order to maintain the current position of the beam 400 after rotating to a certain angle, in some embodiments of the present application, a first limiting hole 1412 is provided on the lifting part 140, a second limiting hole 1321 is provided on the sleeve 130, and a plurality of third limiting holes 124 are provided on the shaft section 121 of the flange shaft 120 at intervals along its outer circumference.

[0100] After turning into place, see Fig.10 The limiting part 300 passes through the first limiting hole 1412, the second limiting hole 1321 and is inserted into the third limiting hole 124 in sequence, so that the lifting part 140 and the sleeve 130 are fixed together with the flange shaft 120, thereby achieving the purpose of locking the crossbeam 400. In this way, the crossbeam 400 can no longer rotate until the limiting part 300 is pulled out of the first limiting hole 1412, the second limiting hole 1321 and the third limiting hole 124, and the force-applying part 200 applies an external rotational force before it rotates again.

[0101] In some embodiments of the present application, the interval arc length of the plurality of third limiting holes 124 may be set according to the angle at which the beam 400 needs to rotate.

[0102] In some embodiments of the present application, when the cross beam 400 is a triangular cross beam, three third limiting holes 124 may be provided, and the axis direction angle between two adjacent third limiting holes 124 of the three third limiting holes 124 is 120 degrees. In this way, each time the cross beam 400 is moved from a stable position (that is, one edge is facing downward after hoisting, see Figure 1 and Figure 2 ) When rotated 120 degrees, there is always one edge facing upwards.

[0103] In some embodiments of the present application, for the hoisting portion 140, see Figure 6 The first limiting hole 1412 penetrates the through hole 1411 , and the penetration direction of the first limiting hole 1412 is perpendicular to the axial direction of the through hole 1411 , and the through hole 1411 and the first limiting hole 1412 are both arranged at the center position of the square steel tube 141 .

[0104] In some embodiments of the present application, see Figure 3The limiting portion 300 as described above may include a limiting pin body and a limiting pin rod.

[0105] The limiting pin body is in the form of a rod, and a through portion (not shown) is formed at the upper end, wherein the through direction of the through portion is perpendicular to the length direction of the limiting pin body.

[0106] The limiting pin rod is also a rod portion, and the limiting pin rod is arranged through the through portion and the two ends extend from the through portion. When the limiting portion 300 is used, the limiting pin rod is convenient for taking the limiting portion 300 and inserting it into the first limiting hole 1412, the second limiting hole 1321 and the third limiting hole 124, see Fig.10 .

[0107] When in use, the force applying portion 200 and the limiting portion 300 need to be aligned with the same assembly portion (see Figure 1 , Figure 3 and Fig. 9 ), therefore, when the force applying portion 200 is used for the first assembly portion 100, the limiting portion 300 is also used for the first assembly portion 100.

[0108] In some embodiments of the present application, since the first assembly portion 100 and the second assembly portion 100' have the same structure, if the force-applying portion 200 is connected to the end face of the first end portion of the shaft segment 121 in the second assembly portion 100', the limiting portion 300 is used for the second assembly portion 100', that is, the limiting portion 300 passes through the first limiting hole on the hanging portion 140' in the second assembly portion 100', the second limiting hole on the bushing (not shown) and the third limiting hole on the shaft segment (not shown).

[0109] In some embodiments of the present application, the force-applying portion 200 can be connected to the end face screw of the first end portion of the shaft segment 121. Therefore, the force-applying portion 200 can be freely selected to be connected to the first end portion of the shaft segment 121 of the flange shaft 120 in the first assembly portion 100, or to be connected to the first end portion of the shaft segment of the flange shaft (not shown) in the second assembly portion 100', according to the operation space or operation requirements, etc., and is not limited here.

[0110] In some embodiments of the present application, see Figure 3 and Figure 5 The force applying part 200 includes an end cover 210 and a wrench 220 .

[0111] The end cover 210 is fixed to the end face of the first end of the shaft segment 121 of the flange shaft 120 in the first assembly part 100, and has an annular surface 211, on which opposite end holes 2111 are opened to facilitate the insertion of the wrench 220 and provide rotational force for the end cover 210 when the wrench 220 is rotated.

[0112] See also Figure 1When the wrench 220 swings downward, the beam 400 rotates clockwise, and when the wrench 220 swings upward, the beam 400 rotates counterclockwise.

[0113] Specifically, see Figure 5 The end cover 210 is a barrel-shaped end cover, and includes the annular surface 211 and the bottom annular surface 212 as described above, and the bottom annular surface 212 closes one side opening of the annular surface 211 .

[0114] In order to achieve the connection between the force applying portion 200 and the end surface of the first end portion of the shaft segment 121 , a plurality of first assembly holes (not shown) are also provided on the end surface of the first end portion.

[0115] Corresponding to the plurality of first assembly holes, a plurality of second assembly holes 2121 are opened on the bottom annular surface 212 of the end cover 210 .

[0116] The corresponding first assembly hole and the second assembly hole 2121 are connected by screws.

[0117] The use of screw connection also facilitates the disassembly of the force applying portion 200 , and can be used for either the first assembly portion 100 or the second assembly portion 100 ′.

[0118] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
