Description

Technical Field

[0001] The present application relates to the field of non-standard machinery manufacturing, and in particular to a vertical lifting device and a detection device. Background Art

[0002] At present, in many equipment manufacturing industries, it is necessary to inspect the inner wall of tubular workpieces, mainly including the surface, welds, openings and other parts of the inner wall of tubular workpieces to check whether the welds are complete, whether there are gaps, whether the inner wall is smooth, whether there are burrs at the openings and other issues.

[0003] In some related technologies, detection devices such as endoscopes are used to check welds, burrs and other problems. Generally, it is necessary to cooperate with a lifting mechanism to extend the detection device into the workpiece for inspection. The lifting mechanism often uses a linear slider module, in which the traditional lifting slider is rigidly connected to the working slider, and the detection device is connected to the working slider. When realizing vertical lifting, the force on the working slider is completely determined by the power of the lifting slider, but there are the following problems:

[0004] Since there is a protruding part inside the workpiece, if the installation position of the lifting mechanism deviates, the protruding part will block the movement of the working slider during its movement. If the power of the lifting slider is too large, the working slider will damage the fixed parts. Summary of the invention

[0005] The embodiments of the present application provide a vertical lifting device and a detection device to solve the problem in the related art that when the installation position of the lifting mechanism deviates, the power of the lifting slide block is too large, which may cause the working slide block to damage the fixed parts.

[0006] In a first aspect, a vertical lifting device is provided, comprising:

[0007] A linear guide assembly, comprising a working slide movable in a vertical direction;

[0008] A linear drive assembly is spaced apart from the linear guide assembly and comprises a lifting slider, wherein the projections of the lifting slider and the working slider in the vertical direction partially overlap, so that the lifting slider pushes the working slider upward;

[0009] The elastic member has a top end connected to the working slider and a bottom end connected to the lifting slider, and is used to pull the working slider down when the working slider is blocked.

[0010] In some embodiments, the working slider has an extension portion;

[0011] The lifting slider is located directly below the extension part; the elastic member is arranged vertically, and two ends thereof are detachably connected to the lifting slider and the extension part through connecting members.

[0012] In some embodiments, the elastic member is a spring with hooks at both ends;

[0013] The connecting member comprises a connecting rod and a limit block arranged at one end of the connecting rod, a screw rod is arranged at the other end of the connecting rod, and a hook is arranged on the connecting rod;

[0014] The lifting slider and the extension part are both provided with connection holes connected with the screw rod.

[0015] In some embodiments, there are multiple connecting holes on the lifting slider and the extension portion, and the connecting holes are vertically spaced apart.

[0016] In some embodiments, the linear guide assembly further includes a guide rail;

[0017] The working slide block also includes a connecting portion, which is slidably arranged on the guide rail, and the extending portion is used to connect the detection member; the connecting portion and the extending portion are connected by connecting bolts.

[0018] In some embodiments, the linear drive assembly further includes a drive member for driving the lifting slider to move up and down.

[0026] The beneficial effects of the technical solution provided by this application include:

[0027] The embodiment of the present application provides a vertical lifting device and a detection device. Since the linear guide component and the linear drive component are arranged at intervals, the working slide block on the linear guide component has an extension portion, and the lifting slide block of the linear drive component contacts the extension portion and pushes the working slide block to rise, and the working slide block and the lifting slide block are connected by an elastic member; when in use, when the working slide block needs to be raised, the lifting slide block pushes the working slide block upward; when the working slide block needs to be lowered, the lifting slide block lowers, the working slide block loses the pushing force, and falls synchronously with the lifting slide block under the action of its own gravity; when the working slide block encounters a raised part of the workpiece during descent and encounters resistance, the working slide block stops falling, the lifting slide block continues to fall, and the elastic member is stretched, thereby avoiding the problem of the lifting slide block driving the working slide block to damage the workpiece.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] The embodiment of the present application provides a vertical lifting device and a detection device to solve the problem in the related art that when the installation position of the lifting mechanism deviates, the power of the lifting slide block is too large, which may cause the working slide block to damage the fixed parts.

[0033] See also Figure 1 , a vertical lifting device, which includes a linear guide component 1, an elastic member 2 and a linear drive component 3.

[0034] The linear guide component 1 includes a working slider 10 that can move in the vertical direction, and the working slider 10 is used to connect the detection part; the linear drive component 3 is arranged at an interval with the linear guide component 1, and the linear drive component 3 includes a lifting slider 30, and the lifting slider 30 partially overlaps with the projection of the working slider 10 in the vertical direction, so that the lifting slider 30 pushes the working slider 10 upward.

[0035] The top end of the elastic member 2 is connected to the working slider 10 , and the bottom end is connected to the lifting slider 30 , and is used to pull the working slider 10 down when the working slider 10 is blocked.

[0036] Through the above structure settings, when using:

[0037] When the working slide block 10 needs to be lifted, the lifting slide block 30 pushes the working slide block 10 upward; when the working slide block 10 needs to be lowered, the lifting slide block 30 is lowered, and the working slide block 10 loses the pushing force provided by the lifting slide block 30, and under the action of its own gravity, it is synchronously lowered with the lifting slide block 30;

[0038] When the working slider 10 encounters a raised portion of the workpiece during descent and encounters resistance, the working slider 10 stops descending, the lifting slider 30 continues to descend, and the elastic member 2 is stretched; then the lifting slider 30 continues to descend, pulling the working slider 10 to slowly descend, and elastic buffering is achieved through the elastic member 2 to prevent the working slider 10 from directly hitting the raised portion of the workpiece, thereby avoiding the problem of the lifting slider 30 driving the working slider 10 to damage the workpiece.

[0039] In addition, when the gravity of the working slide block 10 on the linear guide assembly 1 is insufficient to drive it downward, the elastic member 2 is stretched due to the descent of the lifting slide block 30, and the tension force generated will also drive the working slide block 10 downward.

[0040] In some preferred embodiments, the specific structure in which the projections of the lifting slider 30 and the working slider 10 in the vertical direction partially overlap is as follows:

[0041] The working slide 10 has an extension portion;

[0042] The lifting slider 30 is located directly below the extension portion; the elastic member 2 is vertically arranged, and its two ends are detachably connected to the lifting slider 30 and the extension portion through the connecting member 4 respectively.

[0043] Furthermore, the elastic member 2 is detachably connected in the following manner: the elastic member 2 is a spring with hooks at both ends; the connecting member 4 includes a connecting rod, and a limit block arranged at one end of the connecting rod, a screw is arranged at the other end of the connecting rod, and the hook is arranged on the connecting rod; the lifting slider 30 and the extension part are both provided with connecting holes connected to the screw.

[0044] It can also be a pin-connected structure.

[0045] Furthermore, in order to enable the lifting slider 30 to tighten the working slider 10 with different tensioning forces, the number of connecting holes connected to the connecting rod on the lifting slider 30 and the extension portion is multiple and spaced apart in the vertical direction.

[0046] In some preferred embodiments, in order to facilitate the movement of the working slide 10 and prevent offset, the following settings are made:

[0047] The linear guide assembly 1 further includes a guide rail 11;

[0048] The working slide block 10 also includes a connecting portion, which is slidably mounted on the guide rail 11, and an extending portion is used to connect the detection member; the connecting portion and the extending portion are connected by connecting bolts, so that the working slide block 10 as a whole moves along the guide rail 11 during the movement process without deviation. The guide rail 11 can pass through the connecting portion to avoid falling off during the up and down movement.

[0049] In some preferred embodiments, the linear drive assembly 3 further includes a drive member 31 for driving the lifting slider 30 to move up and down. The drive member 31 includes a lead screw or a pneumatic telescopic rod, which can be selected according to actual conditions.

[0050] The present application also proposes a detection device, which comprises:

[0051] The frame and the vertical lifting device are installed on the frame.

[0052] When the above detection device is in use, the working slider 10 encounters a raised portion of the workpiece during descent. When encountering resistance, the working slider 10 stops descending, the lifting slider 30 continues to descend, and the elastic member 2 is stretched; then the lifting slider 30 continues to descend, pulling the working slider 10 to slowly descend, and elastic buffering is achieved through the elastic member 2 to prevent the working slider 10 from directly hitting the raised portion of the workpiece, thereby avoiding the problem of the lifting slider 30 driving the working slider 10 to damage the workpiece.

[0053] In some preferred embodiments, the detection device further includes a detection sensor 5, which is arranged at the detection target position and is used to detect the positions of the working slide block 10 and the lifting slide block 30;

[0054] When in use, when the lifting slider 30 passes the detection sensor 5 and does not detect the working slider 10, the lifting slider 30 stops moving, indicating that the working slider 10 is blocked, and the position of the entire detection device needs to be adjusted.

[0055] Furthermore, the detection sensor 5 is connected to the frame through a telescopic rod, and the position of the detection sensor 5 can be adjusted at will through the telescopic rod to change the detection target position. The detection sensor 5 does not need to be fixed on the workpiece to be detected, avoiding damage to the workpiece.

[0056] The telescopic rod can be a telescopic gas rod, an electrician's push rod, or a steel rope with adjustable length.

[0057] Principles of this application:

[0058] When the working slide block 10 needs to be lifted, the lifting slide block 30 pushes the working slide block 10 upward; when the working slide block 10 needs to be lowered, the lifting slide block 30 is lowered, and the working slide block 10 loses the pushing force provided by the lifting slide block 30, and under the action of its own gravity, it is synchronously lowered with the lifting slide block 30;

[0059] When the working slider 10 encounters a raised portion of the workpiece during descent and encounters resistance, the working slider 10 stops descending, the lifting slider 30 continues to descend, and the elastic member 2 is stretched; then the lifting slider 30 continues to descend, pulling the working slider 10 to slowly descend, and elastic buffering is achieved through the elastic member 2 to prevent the working slider 10 from directly hitting the raised portion of the workpiece, thereby avoiding the problem of the lifting slider 30 driving the working slider 10 to damage the workpiece.
