Description

Technical Field

[0001] The utility model belongs to the technical field of forklift chassis detection, and in particular relates to a forklift chassis distance detection tool. Background Art

[0002] During the acceptance of forklifts, the distance between the longitudinal beams of the chassis needs to be tested. During the long-term use of the forklift, the chassis may gradually deform due to external impact, and the chassis needs to be regularly inspected with the help of distance detection tools. Existing forklift chassis distance detection tools mostly use tape measures or distance detectors.

[0003] When using a tape measure, you need to pull the tape measure apart and position the tape measure iron sheet after each calibration. The tilt and bend of the tape measure will affect the test results. When using a distance detector, you need to consider factors such as the position of the sensor detection end and the verticality of the sensor installation. The above-mentioned forklift chassis distance detection tooling is not convenient to operate, and the efficiency of forklift chassis distance detection needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a forklift chassis distance detection tooling in order to solve the above-mentioned problem, so as to reduce the difficulty of chassis detection operation and make the distance detection more convenient.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A distance detection tool for a forklift chassis, the forklift chassis includes a pair of longitudinal beams and a plurality of cross beams arranged between the pair of longitudinal beams, the distance detection tool includes a mounting tube and measuring arms slidably arranged on both sides of the mounting tube, a position locking piece is provided between the mounting tube and the measuring arm, the position locking piece is used to adjust the distance between the two measuring arms, a limiting component is provided at the bottom of the mounting tube, and a guide component corresponding to the limiting component is provided at the top of the cross beam. When detecting the distance between the two longitudinal beams of the forklift chassis, first adjust the distance between the two measuring arms through the position locking piece according to the forklift chassis size standard, and then place the limiting component on the cross beam, and the guide component on the cross beam guides the distance detection tool through the limiting component. Pushing the mounting tube toward the inside of the forklift chassis can detect whether the actual distance between the two longitudinal beams meets the standard distance requirement.

[0007] As a further optimization solution of the utility model, the guide component is a convex ridge fixedly arranged on the top of the beam, the limiting component is a plate body fixedly arranged on the bottom of the mounting tube, and a groove corresponding to the convex ridge is provided at the bottom of the plate body.

[0008] As a further optimization solution of the utility model, the measuring arm includes a cylinder and a slide groove opened at one end of the cylinder, and a measuring auxiliary part is provided on the slide groove, and the measuring auxiliary part is used to detect the gap between the measuring arm and the longitudinal beam.

[0009] As a further optimization scheme of the utility model, the measuring auxiliary part includes a mounting plate fixed at one end of the slide slot, and a wedge block slidably arranged inside the slide slot, and the wedge block is connected to the mounting plate spring. When the tooling cannot enter between the two longitudinal beams, it means that the actual distance between the two longitudinal beams is too small. When the distance detection tooling enters between the two longitudinal beams, the friction resistance of the pushing operation is small, which means that the wedge block of the measuring auxiliary part has not been received into the slide slot, and the distance between the longitudinal beams is too large.

[0010] As a further optimization scheme of the utility model, the position locking member includes a double-threaded screw rotatably connected to the inside of the installation tube, a worm wheel fixed in the middle of the screw, and a worm screw meshingly connected to one side of the worm wheel, and the two sides of the screw screw are respectively threadedly connected to the two measuring arms. Through the meshing of the worm screw and the worm wheel, the screw screw drives the two measuring arms to slide in the opposite direction at the same time, and after the adjustment is completed, the distance detection tooling is self-locked through the worm screw and the worm wheel.

[0011] As a further optimization scheme of the utility model, the worm is vertically arranged in the middle of the mounting cylinder, the top and the bottom of the mounting cylinder are rotatably connected to the worm, the upper end of the worm passes through the mounting cylinder, and a handle is fixed to the upper end of the worm.

[0012] As a further optimization scheme of the utility model, support frames are fixedly provided at the bottom of both ends of the inner side of the installation cylinder, and both ends of the screw rod are rotatably connected to the two support frames respectively, and a receiving groove corresponding to the support frame is opened at the bottom of the cylinder.

[0013] As a further optimization solution of the utility model, scale lines are provided on the outer surface of the measuring arm or between the mounting cylinder and the worm.

[0014] As a further optimization solution of the utility model, the position locking member is a positioning pin arranged on both sides of the installation cylinder, and the installation cylinder and the measuring arm are both provided with pin holes corresponding to the positioning pins.

[0015] The beneficial effects of the utility model are:

[0016] 1) The utility model adjusts the distance between the two measuring arms through the position locking part, so that the tooling is equal to the standard distance, and the limiting component is placed on the crossbeam. The guide component cooperates with the limiting component to guide the work. The distance of the forklift chassis can be detected only by pushing the installation cylinder, thereby improving the convenience of forklift chassis distance detection and maintenance efficiency;

[0017] 2) In the process of distance detection, when the tooling cannot enter between the two longitudinal beams, it means that the actual distance between the two longitudinal beams is too small. When the distance detection tooling enters between the two longitudinal beams, the friction resistance of the pushing operation is small, which means that the wedge block of the measuring auxiliary part has not been received into the slide slot and the longitudinal beam distance is too large. The longitudinal beam distance can be fully detected without observing the gap between the measuring arm and the longitudinal beam, which further improves the convenience of distance detection and maintenance efficiency;

[0018] 3) The utility model drives the screw to rotate by cooperating with the worm gear, and drives the two measuring arms at the same time. The two measuring arms slide in opposite directions, so as to adjust the length of the tooling. After the adjustment is completed, the distance detection tooling is self-locking and the length is fixed, so that the tooling can be easily adapted to forklift chassis of different sizes.

DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] First embodiment

[0025] like Figure 1As shown, this embodiment relates to a distance detection tool for a forklift chassis, the forklift chassis includes a pair of longitudinal beams 1 and a plurality of cross beams 2 welded between the pair of longitudinal beams 1, the distance detection tool includes a mounting tube 3 and measuring arms 4 slidably arranged on both sides of the mounting tube 3, the cross section of the measuring arm 4 is rectangular, the inner wall of the mounting tube 3 is in contact with the outer wall of the measuring arm 4, a position locking member 5 is arranged between the mounting tube 3 and the measuring arm 4, the position locking member 5 is used to adjust the distance between the two measuring arms 4, a limiting member 6 is arranged at the bottom of the mounting tube 3, and a guide member 7 corresponding to the limiting member 6 is arranged at the top of the cross beam 2. When detecting the distance between the two longitudinal beams 1 of the forklift chassis, firstly, according to the forklift chassis size standard, the distance between the two measuring arms 4 is fixed to a corresponding size through the position locking member 5, so that the length of the distance detection tool is equal to the standard distance between the two longitudinal beams 1, the longitudinal beam 1 is preferably an I-beam, and the distance between the two longitudinal beams 1 refers to the distance between the opposite end faces of the webs of the two I-beams. Then, the limiting component 6 is placed on the crossbeam 2, and the guide component 7 on the crossbeam 2 guides the distance detection tooling through the limiting component 6. Pushing the installation cylinder 3 toward the inside of the forklift chassis can detect whether the actual spacing between the two longitudinal beams 1 meets the standard spacing requirements, and complete the spacing detection. The distance detection of the forklift chassis can be performed only by pushing the installation cylinder 3. When the distance detection tooling passes through the entire forklift chassis, it can also detect the distance between each part of the two longitudinal beams 1, and the detection tooling can be applied to the distance detection of forklift chassis of different sizes.

[0026] Specifically, the guide component 7 is a convex ridge fixedly mounted on the top of the cross beam 2, and the cross section of the convex ridge is semicircular or conical. The limiting component 6 is a plate body fixedly mounted on the bottom of the mounting tube 3, and a groove corresponding to the convex ridge is provided at the bottom of the plate body. The number of convex ridges on each cross beam 2 is preferably two, and correspondingly, the plate body is also provided with two, or only one plate body with two grooves is provided. In addition, the setting positions of the convex ridge and the groove can also be reversed, that is, a groove is provided at the top of the cross beam 2 to be used as the guide component 7, and a convex ridge is provided at the bottom of the plate body to limit the distance detection tooling.

[0027] like Figure 2 As shown, the position locking member 5 includes a double-threaded screw 51 rotatably connected to the inside of the mounting tube 3, a worm wheel 52 fixedly arranged in the middle of the screw 51, and a worm 53 meshingly connected to one side of the worm wheel 52. The two sides of the screw 51 are respectively threadedly connected to the two measuring arms 4. The worm 53 is vertically arranged in the middle of the mounting tube 3, and the top and bottom of the mounting tube 3 are both rotatably connected to the worm 53. The upper end of the worm 53 penetrates the mounting tube 3, and a handle is fixedly arranged at the upper end of the worm 53. When adjusting the distance between the two measuring arms 4, the worm 53 is rotated by the handle, and the worm 53 meshes with the worm wheel 52, thereby driving the screw 51 to rotate. The threads on both sides of the screw 51 rotate in opposite directions, which can drive the two measuring arms 4 to slide in opposite directions at the same time. After the adjustment is completed, the distance detection tooling is self-locking and the length is fixed, which is convenient for the tooling to adapt to forklift chassis of different sizes.

[0028] In addition, support frames 54 are fixed at the bottom of both ends of the inner side of the installation cylinder 3, and the two ends of the screw 51 are rotatably connected to the two support frames 54 respectively, and a strip-shaped receiving groove 43 corresponding to the support frame 54 is provided at the bottom of the cylinder 41. Two brackets are also provided in the middle of the installation cylinder 3, and the two brackets are located on both sides of the worm gear 52 to support the screw 51. The receiving groove 43 is provided at the bottom of the cylinder 41, which can reduce the water vapor and dust entering the measuring arm 4 and the installation cylinder 3, and extend the service life of the tooling. A scale line is provided on the outer surface of the measuring arm 4 or between the installation cylinder 3 and the worm 53, and a scale line is provided between the installation cylinder 3 and the worm 53, which is located on the upper surface of the installation cylinder 3 and is arranged around the worm 53. A dot-shaped marker is provided on the outer side of the upper part of the worm 53 to display the rotation angle of the worm 53, so that the operator can control the adjustment process of the measuring arm 4 conveniently.

[0029] For further information, see Figure 2 The measuring arm 4 includes a cylinder 41 and a slide groove 42 opened at one end of the cylinder 41 away from the mounting cylinder 3. The slide groove 42 is provided with a measuring auxiliary component 8, which is used to detect the gap between the measuring arm 4 and the longitudinal beam 1. Specifically, the measuring auxiliary component 8 includes a mounting plate 81 fixedly arranged at the inner end of the slide groove 42, and a wedge block 82 slidably arranged inside the slide groove 42, and the wedge block 82 is spring-connected with the mounting plate 81, that is, a spring 83 is fixedly arranged between the wedge block 82 and the mounting plate 81. In a natural state, one side of the wedge block 82 extends outward from the slide groove 42.

[0030] When the installation cylinder 3 is pushed to detect the distance, the distance detection tooling can be just between the two longitudinal beams 1, and the two measuring arms 4 can fit the two longitudinal beams 1 respectively, indicating that the actual distance between the two longitudinal beams 1 meets the standard distance. At this time, the wedge block 82 is squeezed into the inside of the slide 42 by the longitudinal beam 1, and the spring 83 is in a compressed state. When the installation cylinder 3 is pushed, the operator can feel the friction resistance generated between the wedge block 82 and the longitudinal beam 1. When the distance detection tooling cannot enter the area between the two longitudinal beams 1, it means that the actual distance between the two longitudinal beams 1 is too small; when the distance detection tooling enters the area between the two longitudinal beams 1, the friction resistance generated when the distance detection tooling is pushed is small, which means that the wedge block 82 is not received in the slide 42, and the actual distance between the two longitudinal beams 1 is too large. The operator does not need to observe the gap between the measuring arm 4 and the longitudinal beam 1, and can fully detect the distance between the longitudinal beams 1, further improving the convenience of distance detection and maintenance efficiency.

[0031] Second embodiment

[0032] like Figure 3As shown, the present embodiment relates to a forklift chassis distance detection tooling, which differs from the first embodiment in that the position locking member 5 is different in structure. The position locking member 5 of the present embodiment is a positioning pin 55 arranged on both sides of the mounting cylinder 3, and the mounting cylinder 3 and the measuring arm 4 are both provided with pin holes corresponding to the positioning pin 55. Among them, the pin holes on the measuring arm 4 are two rows of through holes respectively arranged at the top and bottom of the cylinder 41; the pin holes on the mounting cylinder 3 are a row of through holes arranged at the top of the mounting cylinder 3, and a row of countersunk holes arranged at the bottom of the mounting cylinder 3. The tooling can be provided with a certain number of pin holes on the measuring arm 4 and the mounting cylinder 3 according to actual needs to adapt to forklift chassis of different sizes. The spacing adjustment accuracy of the two measuring arms 4 of the present embodiment is better, but stepless adjustment cannot be achieved, and it can be applied to factory testing and maintenance work with fewer types of forklift chassis sizes. In addition, the positioning pin 55 of the present embodiment can also be replaced by a threaded fastener.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
