Description

Technical Field

[0001] This utility model relates to a telescopic crane outrigger verticality detection rod, belonging to the technical field of crane auxiliary testing equipment. Background Technology

[0002] Currently, cranes are widely used in construction, cargo loading and unloading, and the verticality of their outriggers is crucial to the safe and stable operation of the crane. Poor verticality of the outriggers may cause the crane to tilt or sway during operation, or even cause serious safety accidents, resulting in personal injury and property damage.

[0003] Traditional methods for checking the verticality of crane outriggers typically rely on manual measurement using simple tools such as plumb lines and right-angle rulers. However, this method is not only inefficient but also susceptible to human error in measurement accuracy, and it cannot achieve rapid multi-angle rotation testing after fixing, thus having limitations. Therefore, to solve these problems, there is an urgent need to design a new testing rod for checking the verticality of crane outriggers. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a telescopic crane outrigger verticality detection rod, which features a simple structure, easy operation, high detection efficiency, and the ability to perform multi-angle rotation detection.

[0005] The present invention relates to a retractable crane outrigger verticality detection rod, comprising:

[0006] The main rod mechanism consists of a main rod and an outer tube. The main rod is slidably fitted inside the outer tube, with its upper end extending outside the outer tube. The main rod is able to slide and pull within the outer tube, forming a telescopic structure. A rotating shaft is installed through the top of the main rod along its cross-sectional direction. Connecting sleeves are fixedly installed at both ends of the rotating shaft. A scale pointer is fixedly connected to the bottom of the outer circumference of each connecting sleeve.

[0007] A rotating block is rotatably connected to the main rod via a rotating shaft; an arc-shaped scale plate is fixedly connected to both sides of the rotating block; the scale plate has graduations on its surface, and the scale plates on both sides are symmetrically arranged front and back.

[0008] A connecting plate, one end of which is rotatably connected to a rotating block via a rotating shaft; the other end of the connecting plate is hinged to two connecting blocks, which are symmetrically arranged.

[0009] The clamping assembly consists of two symmetrically arranged clamping parts; one end of each clamping part is fixedly connected to a connecting block; the other end of each clamping part is fixedly connected to a side plate with a U-shaped structure; a splicing block is rotatably connected to the inner side of the side plate; a limit hole is provided on the splicing block, and the clamping assembly can be limited by installing bolts in the limit hole of the splicing block.

[0010] Furthermore, a limiting ring for preventing the main rod from detaching is fixedly installed inside the outer tube.

[0011] Furthermore, a counterweight is fixed at the bottom of the outer tube. Equipping the bottom of the outer tube with a counterweight enables the main rod mechanism to maintain a more stable vertical state.

[0012] Furthermore, the rotating block is provided with a square hole; the end of the main rod extends into the square hole and is movably connected to the rotating block through a rotating shaft, with both ends of the rotating shaft passing through the rotating block and screwed and fixed to the connecting sleeve.

[0013] Furthermore, the scale discs and scale pointers on both sides correspond one-to-one, the scale discs and scale pointers are matched, and the scale pointers are oscillating on the outer surface of the scale discs; if the crane outriggers are vertical, the main rod mechanism is parallel to the outriggers, and the lower end of the scale pointers points to the 0 mark on the scale disc.

[0014] Furthermore, a support plate is fixed in the middle of the connecting plate. By fixing the longitudinally arranged support plate, the overall connectivity of the connecting plate can be strengthened, thereby improving the support and stability during testing.

[0015] Compared with existing technologies, the telescopic crane outrigger verticality detection rod of this invention, by clamping and fixing the detection rod to the crane outrigger, can quickly perform multi-angle rotation detection without the need for frequent manual adjustment of the measuring tool position, saving a lot of measurement time and significantly improving the efficiency of detecting the verticality of the crane outrigger. At the same time, by utilizing the counterweight setting, the main rod mechanism can be stably verticalized, and the angle can be precisely measured by the precise coordination of the scale plate and the scale pointer, avoiding interference from human factors and greatly improving the measurement accuracy. This effectively solves the problem of low accuracy in traditional detection methods, enabling more accurate detection of the verticality of the crane outrigger and ensuring the safety of crane operation.

[0023] Example 1:

[0024] like Figures 1 to 4 The telescopic crane outrigger verticality detection rod shown includes...

[0025] The main rod mechanism consists of a main rod 3 and an outer tube 3013. The main rod 3 is slidably fitted inside the outer tube 3013, with its upper end extending outside the outer tube 3013. A limiting ring 3012 is fixedly installed inside the outer tube 3013 to prevent the main rod 3 from detaching. The main rod 3 is fitted inside the outer tube 3013 and can slide and pull within the outer tube 3013, with the limiting ring 3012 preventing detachment, thus forming a telescopic structure. A counterweight 3014 is also fixed at the bottom of the outer tube 3013, which helps the main rod mechanism maintain a more stable vertical position. A rotating shaft is installed through the top of the main rod 3 along its cross-sectional direction. Connecting sleeves 301 are fixedly installed at both ends of the rotating shaft. A scale pointer 3011 is fixedly connected to the bottom of the outer circumference of each connecting sleeve 301.

[0026] A rotating block 201 is rotatably connected to the main rod 3 via a rotating shaft. Specifically, the rotating block 201 has a square hole. The end of the main rod 3 extends into the square hole and is movably connected to the rotating block 201 via the rotating shaft. Both ends of the rotating shaft pass through the rotating block 201 and are screwed and fixed to the connecting sleeve 301. Arc-shaped scale discs 2011 are fixedly connected to both sides of the rotating block 201. The surface of the scale discs 2011 is provided with scales, and the scale discs 2011 on both sides are symmetrically arranged. The scale discs 2011 on both sides correspond one-to-one with the scale pointers 3011. The scale discs 2011 and the scale pointers 3011 are matched, and the scale pointers 3011 swing on the outer surface of the scale discs 2011. If the crane outriggers are vertical and the main rod mechanism is parallel to the outriggers, the lower end of the scale pointers 3011 points to the 0 mark on the scale discs 2011.

[0027] A connecting plate 1 is provided, one end of which is rotatably connected to a rotating block 201 via a rotating shaft 2; two connecting blocks 1011 are hinged to the other end of the connecting plate 1, and the two connecting blocks 1011 are symmetrically arranged; a support plate 101 is also fixed in the middle of the connecting plate 1, and the overall connection of the connecting plate 1 can be strengthened by fixing the longitudinally arranged support plate 101, so as to improve the support and stability during the test.

[0028] The clamping assembly 1012 consists of two symmetrically arranged clamping parts. One end of each clamping part is fixedly connected to the connecting block 201. The other end of each clamping part is fixedly connected to a side plate 1013 with a U-shaped structure. A splicing block 1014 is rotatably connected to the inner side of the side plate 1013. A limiting hole 1015 is provided on the splicing block 1014. By installing bolts in the limiting holes 1015 of the splicing block 1014, the two splicing blocks 1014 on both sides are connected, thereby limiting the clamping assembly 1012.

[0029] The retractable crane outrigger verticality detection rod of this utility model, such as Figure 5 and Figure 6 As shown, in use, the connecting plate 1 is first clamped onto the crane accessory 4 of the crane outrigger structure by the connecting block 1011 with the opposite hinge. At this time, the longitudinally arranged support plate 101 supports and stabilizes the connecting plate 1, ensuring the stability of the detection rod installation. Then, by installing bolts in the limiting hole 1015 of the splicing block 1014, the clamping component 1012 is limited to ensure that the detection rod is tightly fixed to the crane outrigger and avoids shaking during the measurement process.

[0030] The rotating block 201 is installed at the end of the connecting plate 1 via the rotating shaft 2. The main rod 3 of the main rod mechanism is rotatably connected inside the rotating block 201. After the detection rod is installed, the main rod mechanism will naturally droop under the action of gravity. The circular limiting ring 3012 at the bottom of the main rod mechanism can prevent the outer tube 3013 from falling off. The counterweight 3014 connected to the bottom of the outer tube 3013 can make the main rod mechanism more stable and maintain a vertical state. If the crane outrigger is vertical, the main rod mechanism should be parallel to the outrigger.

[0031] Since the rotating block 201 can rotate around the rotating shaft 2, it drives the main rod mechanism to rotate at multiple angles. During the rotation of the main rod mechanism, the connecting sleeve 301 rotates together with the main rod mechanism. The scale pointer 3011 fixed at the bottom of the outer peripheral surface of the connecting sleeve 301 will cooperate with the arc-shaped scale disk 2011 fixed on the bottom surface of the rotating block 201. By observing the scale correspondence between the scale pointer 3011 and the scale disk 2011, the rotation angle of the main rod mechanism relative to the rotating block 201 can be determined, and then the verticality of the crane outrigger can be detected from different angles to achieve multi-angle measurement.

[0032] If the length of the detection rod needs to be adjusted to meet the detection requirements of different heights, the outer tube 3013 can be stretched or contracted. Since the outer tube 3013 is sleeved on the outside of the main rod and the limiting ring 3012, and the counterweight 3014 is fixed at the bottom of the outer tube 3013, the overall stability of the detection rod can be guaranteed during the stretching or contraction process, and the accuracy of the verticality measurement will not be affected.

[0033] The above embodiments are merely preferred embodiments of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the scope of the present utility model patent application.
