Description
TECHNICAL FIELD
[0001] The utility model relates to the field of production equipment especially a clamping device for guide rail detection. BACKGROUND
[0002] With the increasing number of high-rise buildings, the demand for elevators also gradually increases, and most of the elevators are guide rail type, that is, the car runs along the fixed guide rail during the elevator operation.
[0003] In the traditional guide rail production and processing process, the arc is easy to become larger during production due to the extension of the guide rail, and when the arc exceeds the specified range, it will affect the running stability of the high-speed elevator, so it is necessary to detect the straightness of the guide rail after the guide rail production is completed, and when detecting the guide rail, the existing straightness detection device usually needs to stabilize the guide rail on the detection table through the clamping device, and the mechanical structure of the traditional clamping device is relatively complex when clamping the guide rail, which is not conducive to simple and firm guide rail clamping and the traditional clamping device cannot adjust the distance between the clamping devices according to different specifications of the guide rail, resulting in poor flexibility of the clamping device, so improvement is still needed. SUMMARY
[0004] The utility model discloses a clamping device for guide rail detection, which comprises a base, a support is arranged on the base, an installation seat is arranged at the middle position of the lower end of the support, a detection table is installed on the installation seat, a guide rail is placed on the detection table, an installation plate is installed at the upper end of the support, a gas cylinder is installed on the installation plate, a push rod is arranged at the front end of the gas cylinder, a shaft sleeve is arranged at the front end of the push rod, a fixed arm is horizontally arranged on the left and right legs of the support, a connecting rod is arranged at the front end of the fixed arm, an axis is arranged between the middle position of the connecting rod and the fixed arm and connected through the axis, the upper end of the connecting rod is installed in the shaft sleeve, and a fixed frame is arranged at the lower end of the connecting rod.
[0005] Preferably, the outer part of the rolling wheel is covered with a rubber layer.
[0006] The utility model discloses the beneficial effect is: the utility model discloses the structure design is reasonable, convenient to use, through the setting of connecting rod, utilizes the gas cylinder to push the connecting rod and can simply and conveniently hold the guide rail, can also be convenient for adapting to different specifications of T type guide rail, improves the use simplicity and flexibility of the clamping device. BRIEF DESCRIPTION OF DRAWINGS
[0007] The utility model will be explained through example and the mode of referring to the attached drawing, wherein:
[0008] Figure 1 It is the whole structure schematic diagram of the utility model;
[0009] Figure 2 is the partial structure diagram in the utility model Figure 1 ;
[0010] In the figure: 1, base; 2, support; 3, mounting seat; 4, detection table; 5, guide rail; 6, fixed arm; 7, mounting plate; 8, air cylinder; 9, push rod; 10, shaft sleeve; 11, connecting rod; 12, pivot; 13, fixed frame; 14, rolling wheel. DETAILED DESCRIPTION
[0011] All features disclosed in this specification, and / or all steps of any methods or processes disclosed in this specification, can be combined in any manner, except where features or steps are mutually exclusive.
[0012] Any feature in the present specification, unless explicitly stated to the contrary, can be replaced by alternative features serving the same, equivalent or similar purpose, unless specifically stated to the contrary. Thus, unless stated otherwise, each feature can be one of many alternative features.
[0013] As Figure 1 , 2 shown in the utility model, a kind of guide rail detection clamping device, including base 1, the base 1 is provided with support 2, the lower middle position of support 2 is provided with mounting seat 3, detection table 4 is installed on mounting seat 3, guide rail 5 is placed on detection table 4, the upper end of support 2 is installed with mounting plate 7, air cylinder 8 is installed on mounting plate 7, the front end of air cylinder 8 is provided with push rod 9, the front end of push rod 9 is provided with shaft sleeve 10, the left and right two legs of support 2 are both transversely provided with fixed arm 6, the front end of fixed arm 6 is provided with connecting rod 11, connecting rod 11 is provided with pivot 12 between the middle position and fixed arm 6 and is connected by pivot 12, the upper end of connecting rod 11 is installed in shaft sleeve 10, the lower end of connecting rod 11 is provided with fixed frame 13, rolling wheel 14 is provided in fixed frame 13.
