Description

Technical Field

[0001] This invention belongs to the field of rail transit engineering surveying technology, specifically a rail transit engineering installation surveying device. Background Technology

[0002] In rail transit engineering, various measurements are required after the rails are laid and installed. Among these, measuring the levelness of the rails is of paramount importance, as it relates to the safety of train operation. In existing technologies, laser measuring instruments are typically attached to the rails, with the connection point being a crossbar structure. However, in these existing technologies, the contact surface between the crossbar and the rails needs to be constantly adjusted, leading to unavoidable wear. This is especially true when the rail surface is uneven or the rails on both sides are not level, which can easily cause irregular wear between the contact surface of the crossbar and the rails, thus affecting the initial leveling accuracy of the laser measuring instrument. Summary of the Invention

[0003] The purpose of this invention is to provide a measurement device for rail transit engineering installation, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a rail transit engineering installation and measurement device, comprising a horizontal plate slidably installed on the top of a rail, a laser measuring instrument installed on the top of the horizontal plate, brackets installed on both the left and right sides of the laser measuring instrument, and an installation mechanism installed at the bottom of the brackets;

[0005] The installation mechanism includes a receiving cylinder and a fixed column fixedly connected to the middle and both sides of the bottom surface of the support. A spring and a telescopic column are movably sleeved inside the receiving cylinder. A fixed plate is fixedly connected to the bottom end of the telescopic column. A spring is elastically connected to the bottom of the fixed plate, and a movable plate is elastically installed through the spring. Multiple sets of rotating cylinders are rotatably installed inside the movable plate. The outer surface of the rotating cylinder abuts against the rail.

[0006] Two sets of fixed columns are symmetrically distributed on the left and right sides of the rail. A timing plate is movably sleeved inside the fixed column. A connecting seat is fixedly connected inside the timing plate. A connecting rod is fixedly connected to the bottom of the connecting seat. An abutting cylinder is fixedly connected to the bottom of the connecting rod. The abutting cylinder abuts against the left and right sides of the rail. A lateral cylinder that abuts against the sides of the rail is movably sleeved on the outer surface of the connecting rod.

[0007] As a preferred embodiment of the present invention, each of the four corners of the bottom of the fixed plate is fixedly connected with a pin, and each of the four corners of the top of the movable plate is fixedly connected with a guide ring. The pins are adapted to be inserted into the movable plate and abut against the movable plate.

[0008] In a preferred embodiment of the present invention, the first spring is located at the top of the telescopic column, and the two ends of the first spring are elastically connected to the inner wall of the receiving cylinder and the telescopic column, respectively, and the first spring is compressed and disposed in the receiving cylinder.

[0009] As a preferred embodiment of the present invention, the non-hinged end of the synchronization plate is designed as a semi-circular arc and abuts against the top of the fixed plate, and the synchronization plate is designed as an inclination.

[0010] In a preferred embodiment of the present invention, the axis of the connecting rod is vertically distributed, the outer surface of the abutting cylinder abuts against the transition at the bottom of the upper end of the rail, and the abutting cylinder is made of hard rubber.

[0011] As a preferred embodiment of the present invention, the bottom of the outer surface of the connecting rod is provided with a groove, the lateral cylinder is movably sleeved in the groove, the outer ring surface of the lateral cylinder has an arc transition design, and the lateral cylinder is made of stainless steel.

[0012] As a preferred embodiment of the present invention, the telescopic column has a "T" shaped cross-section, and the telescopic column, spring one, and spring two are longitudinally coaxially distributed.

[0013] As a preferred embodiment of the present invention, the axis of the abutment cylinder is always located on the outer side of the left and right sides of the rail, and the synchronization plate is in a horizontal state under initial conditions.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The moving module of this equipment has been redesigned to reduce wear and improve measurement accuracy. A synchronous plate and connecting seat are rotatably mounted on fixed columns located on the left and right sides of the bottom of the support. This causes the contact cylinder to abut against the top of the rail on both sides. During downward pressure, the connecting rod, connecting seat, and synchronous plate rotate synchronously around the axis of the fixed columns. The non-hinged end of the synchronous plate presses downward against the fixed plate, thereby elastically transmitting pressure to the moving plate and rotating cylinder through the compression spring. This causes the rotating cylinder to abut against the top of the rail, creating rolling friction. As the device moves along the rail surface, the rolling adaptation contact between the rotating cylinder and the rail surface provides support, avoiding irregular wear caused by sliding friction in traditional technologies, thus improving the calibration accuracy of the laser measuring instrument.

[0016] 2. Simultaneously, the connecting rod rotates when it comes into contact with the rail, causing the connecting rod and the lateral cylinders to be positioned on the left and right sides of the rail respectively. The flexible characteristics of the contact cylinders make contact with the corner at the bottom of the upper end of the rail, forming a limiting effect for the installation mechanism after installation. Then, the lateral cylinders rotate to a vertical position and make contact with the left and right sides of the rail. As the device moves along the surface of the rail, the symmetrically distributed lateral cylinders on the left and right sides rotate and make contact with the rail, preventing the installation mechanism from shifting, thereby improving the practicality of the device.

[0017] 3. Finally, the elastic compressible space between the fixed plate and the moving plate is maintained by the fitting plug design with plug and guide ring. When the synchronous plate rotates continuously and abuts against the fixed plate, the relationship between the plug and guide ring provides vertical guidance. Then, the continuously compressible spring prevents jamming when the rotating cylinder abuts against the top of the rail, thus realizing the elastic potential energy storage and conversion function of pressure.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 8 As shown, this embodiment of the invention provides a measurement device for rail transit engineering installation, including a horizontal plate 2 that is slidably installed on the top of a rail 1, a laser measuring instrument 4 installed on the top of the horizontal plate 2, brackets 3 installed on both the left and right sides of the laser measuring instrument 4, and an installation mechanism 5 installed at the bottom of the brackets 3.

[0029] The installation mechanism 5 includes a receiving cylinder 52 and a fixed column 51 fixedly connected to the middle and both sides of the bottom surface of the bracket 3. The receiving cylinder 52 is movably sleeved with a spring 53 and a telescopic column 54. The bottom end of the telescopic column 54 is fixedly connected to a fixed plate 55. The bottom of the fixed plate 55 is elastically connected to a spring 56, and a movable plate 58 is elastically installed through the spring 56. Multiple sets of rotating cylinders 59 are rotatably installed inside the movable plate 58. The outer surface of the rotating cylinders 59 abuts against the rail 1.

[0030] Two sets of fixed posts 51 are symmetrically distributed on the left and right sides of the rail 1. A synchronous plate 511 is movably sleeved inside the fixed post 51. A connecting seat 512 is fixedly connected inside the synchronous plate 511. A connecting rod 513 is fixedly connected to the bottom of the connecting seat 512. An abutting cylinder 515 is fixedly connected to the bottom of the connecting rod 513. The abutting cylinder 515 abuts against the left and right sides of the rail 1. A lateral cylinder 514 that abuts against the sides of the rail 1 is movably sleeved on the outer surface of the connecting rod 513.

[0031] The moving module of this device has been redesigned to reduce wear and improve measurement accuracy. A synchronous plate 511 and a connecting seat 512 are rotatably mounted on fixed columns 51 located on the left and right sides of the bottom of the support 3. This causes the contact cylinder 515 to abut against the left and right sides of the top of the rail 1. During downward pressure, the connecting rod 513, the connecting seat 512, and the synchronous plate 511 rotate synchronously around the axis of the fixed column 51. The non-hinged end of the synchronous plate 511 presses downward against the fixed plate 55, thereby elastically transmitting pressure to the moving plate 58 and the rotating cylinder 59 via the compression spring 56. This causes the rotating cylinder 59 to abut against the top of the rail 1, creating conditions for rolling friction. As the device moves along the surface of the rail 1, the rolling adaptation contact between the rotating cylinder 59 and the surface of the rail 1 provides support, avoiding irregular wear caused by sliding friction in traditional technologies, thus improving the calibration accuracy of the laser measuring instrument 4.

[0032] Simultaneously, the connecting rod 513 rotates when it comes into contact with the rail 1, causing the connecting rod 513 and the lateral cylinder 514 to be positioned on the left and right sides of the rail 1 respectively. The flexible feature of the contact cylinder 515 comes into contact with the corner at the bottom of the upper end of the rail 1, forming a limiting effect of the installation mechanism 5 after installation. Then, the lateral cylinder 514 rotates to a vertical position and comes into contact with the left and right sides of the rail 1. When the device moves along the surface of the rail 1, the lateral cylinders 514, which are symmetrically distributed on the left and right sides, rotate and come into contact with the rail 1, preventing the installation mechanism 5 from shifting, thereby improving the practicality of the device.

[0033] Finally, the elastic compressible space between the fixed plate 55 and the moving plate 58 is maintained by the matching plug design with the plug 57 and the guide ring 510. When the synchronous plate 511 continues to rotate and abuts against the fixed plate 55, the relationship between the plug 57 and the guide ring 510 provides a vertical guiding function. Then, the continuously compressible spring 56 is used to prevent the jamming phenomenon that occurs when the rotating cylinder 59 abuts against the top of the rail 1, thus realizing the elastic potential energy storage and conversion function of pressure.

[0034] Among them, the four corners of the bottom of the fixed plate 55 are fixedly connected with the insert post 57, and the four corners of the top of the movable plate 58 are fixedly connected with the guide ring 510. The insert post 57 is adapted to be inserted into the movable plate 58 and abuts against the movable plate 58.

[0035] The insert 57 is fitted between the guide rings 510 to prevent the moving plate 58 and the fixed plate 55 from shifting during relative movement, thus providing a guiding function. When the bottom end of the insert 57 abuts against the moving plate 58, the mounting mechanism 5 is fully supported and mounted on the top of the rail 1, and the bracket 3 and the cross plate 2 no longer move downward.

[0036] Among them, spring 53 is located at the top of telescopic column 54, and the two ends of spring 53 are elastically connected to the inner wall of receiving cylinder 52 and telescopic column 54 respectively. Spring 53 is compressed and set in receiving cylinder 52.

[0037] The receiving cylinder 52 is fixedly connected to the bracket 3, and the fixed plate 55 and the moving plate 58 are hoisted and supported by the telescopic column 54. The flexible contact between the fixed plate 55 and the bracket 3 is transformed into a rigid contact by the compression spring 53. When the spring 53 is compressed to its limit, there is no buffer gap between the bracket 3 and the telescopic column 54, thereby supporting the bracket 3 and the horizontal plate 2.

[0038] Among them, the non-hinged end of the synchronization plate 511 is designed with a semi-circular arc and abuts against the top of the fixed plate 55. The synchronization plate 511 is designed with an inclination.

[0039] The inner end of the synchronizing plate 511 is designed with a semi-circular arc. This part directly abuts against the top of the fixed plate 55. When the abutting cylinder 515 rotates and tilts through the connecting rod 513 and the connecting seat 512, it can apply downward pressure to the fixed plate 55, forcing it to move downward and driving the rotating cylinder 59 to abut against the top of the rail 1.

[0040] As the synchronous plate 511 continues to rotate and abuts against the fixed plate 55, the vertical guiding function is provided through the relationship between the insert post 57 and the guide ring 510. Then, the continuously compressible spring 56 is used to prevent jamming when the rotating cylinder 59 abuts against the top of the rail 1, thus realizing the elastic potential energy storage and conversion function of the pressure.

[0041] Among them, the axis of the connecting rod 513 is vertically distributed, and the outer surface of the abutting cylinder 515 abuts against the transition at the bottom of the upper end of the rail 1. The abutting cylinder 515 is made of hard rubber.

[0042] When the axis of the connecting rod 513 is vertical, the relative position between the installation mechanism 5 and the rail 1 no longer changes. At this time, the connecting rod 513 abuts against both sides of the upper bottom of the rail 1 and forms a limit, maintaining the stability of the installation mechanism 5 after it is installed on the rail 1.

[0043] Among them, the bottom of the outer surface of the connecting rod 513 has a groove, and the lateral cylinder 514 is movably sleeved in the groove. The outer ring surface of the lateral cylinder 514 has a rounded transition design, and the lateral cylinder 514 is made of stainless steel.

[0044] The lateral cylinder 514 is movably sleeved in the groove opened on the outer surface of the connecting rod 513. Its function is to prevent the installation mechanism 5 from shifting when the lateral cylinder 514 is rotated to a vertical position and abuts against the left and right sides of the rail 1. When the device moves along the surface of the rail 1, the lateral cylinders 514 symmetrically distributed on the left and right sides rotate and abut against the rail 1, thereby improving the practicality of the device.

[0045] The telescopic column 54 has a "T" shaped cross-section, and the telescopic column 54, spring 1 53 and spring 2 56 are coaxially distributed longitudinally.

[0046] like Figure 5As shown, the "T"-shaped telescopic column 54 is fitted inside the receiving cylinder 52 and is elastically installed under the action of spring 53, thus achieving limited hoisting. On the one hand, this design can prevent the fixed plate 55 connected to the telescopic column 54 from falling downwards. On the other hand, the buffer space generated by the compression of spring 53 can prevent the abutment cylinder 515 from rotating and tilting and the rotating cylinder 59 from jamming due to downward movement. By compressing spring 56, the pressure is elastically transmitted to the moving plate 58 and the rotating cylinder 59, so that the rotating cylinder 59 abuts against the top of the rail 1, forming the conditions for rolling friction. When the device moves along the surface of the rail 1, the rolling adaptation contact support between the rotating cylinder 59 and the surface of the rail 1 avoids the irregular wear caused by sliding friction in the traditional technology, thereby improving the calibration accuracy of the laser measuring instrument 4.

[0047] Among them, the axis of the contact cylinder 515 is always located on the outer side of the left and right sides of the rail 1, and the synchronization plate 511 is in a horizontal state under the initial conditions.

[0048] The axis of the abutment cylinder 515 must always be located on the outer side of the left and right sides of the rail 1. Only in this way can the abutment cylinder 515 tilt outward synchronously by rotating when it abuts against the two corners at the top of the rail 1, thereby driving the connecting rod 513, the connecting seat 512 and the synchronous plate 511 to tilt and abut synchronously, so as to realize the synchronous pressing function of the fixed plate 55.

[0049] Working principle:

[0050] When using this device: Install the horizontal plate 2 onto the rail 1. First, position the bracket 3, along with the mounting mechanism 5, directly above the rail 1, aligning the axis of the receiving cylinder 52 with the centerline of the rail 1. Ensure the outer surfaces of the left and right abutment cylinders 515 abut against the top of the rail 1 on both sides. Press down on the device, causing the abutment cylinders 515 to be stressed and roll against the outer surface of the rail 1. The abutment cylinders 515 will rotate, causing the lateral cylinder 514, connecting seat 512, and synchronous plate 511 to rotate around the axis of the fixed column 51. This causes the synchronous plate 511 to rotate downwards at one end abutting against the fixed plate 55, continuously pressing down on the fixed plate 55. This causes the spring 56, moving plate 58, and rotating cylinder 59 to move downwards, bringing the rotating cylinder 59 into contact with the top of the rail 1. Spring 56 is also continuously compressed. The telescopic column 54 is supported by the rail 1 and moves downward relative to the inside of the receiving cylinder 52, compressing spring 53. As the installation mechanism 5 moves downward as a whole, the abutment cylinder 515 moves in a rolling state to the left and right sides of the bottom of the upper end of the rail 1. At this time, the axis of the abutment cylinder 515 is close to the axis of the rail 1, and the axis of the connecting rod 513 is vertically distributed. At this time, the outer surface of the lateral cylinder 514 abuts against the left and right sides of the rail 1. Spring 53 is compressed to the limit. The fixing plate 55 drives the insert 57 to abut against the top of the moving plate 58. The guide ring 510 is used for vertical limitation, and the moving plate 58 and the rotating cylinder 59 are continuously pressed, so that the outer surface of the rotating cylinder 59 always abuts against the top of the rail 1.

[0051] When the device needs to move along the top of the rail 1 during operation, it will cause the lateral cylinder 514 and the rotating cylinder 59 to roll and rub against each other with the surface of the rail 1, thereby reducing wear.
