[0025] See also Figure 1-3 , the embodiments of the utility model are further described;

[0026] A temporary clamping device for track construction, comprising: a U-shaped steel 1, a transmission assembly, an electric clamping piece, a distance meter and a lifting assembly, wherein the transmission assembly is installed at the lower part of the U-shaped steel 1, two electric clamping pieces are provided and are respectively installed at both sides of the inner wall of the U-shaped steel 1, and a plurality of through holes 10 are opened on the clamping end of the electric clamping piece, two distance meters are provided and are respectively installed at both sides of the inner wall of the U-shaped steel 1, and the distance meter corresponds to one of the through holes 10, and the lifting assembly is installed at the bottom of the U-shaped steel 1;

[0027] Exemplarily, the transmission component can be a number of transmission rollers 7, which are all rotatably connected to the bottom of the U-shaped steel 1. When transmitting on the track, they need to be pushed by manpower or electric equipment. They can also be electric transmission rollers, which are more labor-saving. The rangefinder can be a laser rangefinder, an infrared rangefinder, a phase rangefinder or other rangefinders. A detachable connection method, such as a bolt connection, is used between the lifting component and the U-shaped steel 1 to facilitate assembly or disassembly of the lifting component and the U-shaped steel 1.

[0028] If the track to be installed needs to be installed at a location with a certain height and angle, before the device is used, the bottom of the lifting component is fixed to the ground by screws. It should be noted that in the initial state, the lifting height value of the lifting component is the smallest, which is convenient for placing the track to be installed from the ground on the transmission component. After the track is transmitted to the designated location, the distance L0 from the distance meter to the clamping end of the power clamp is measured, and then the distance meter is powered on. The light source generated by the distance meter will pass through the through hole 10 to test the distance L1 between itself and the track. The distance value L moved by the clamping end of the power clamp is L=L1-L0, which can realize the precise clamping of the track by the two power clamps. Then, the lifting component is started to adjust the height and angle of the U-shaped steel 1, so as to facilitate the installation of the track at the location with the required height and angle.

[0029] If the track to be installed only needs to be installed on the ground, the lifting assembly can be removed from the bottom of the U-shaped steel 1, and then the U-shaped steel 1 can be fixed on the ground. After that, the track to be installed can be placed on the transmission assembly, and manpower or electricity can be used to transmit the track into the U-shaped steel 1. After the track is transmitted to the designated location, the distance L0 from the distance meter to the clamping end of the power clamp is measured, and then the distance meter is powered on. The light source generated by the distance meter will pass through the through hole 10 to test the distance L1 between itself and the track. The distance value L moved by the clamping end of the power clamp is L=L1-L0, which can achieve the precise clamping of the track by the two power clamps.

[0030] The electric clamping member specifically includes an electric push rod 6 and a clamping plate 9. At least two electric push rods 6 are provided and are horizontally mounted on the U-shaped steel 1. The clamping plate 9 is located inside the U-shaped steel 1 and fixed at the output end of the electric push rod 6. A through hole 10 is opened on the clamping plate 9.

[0031] When clamping the track, the electric push rod 6 is connected to the power supply, and the electric push rod 6 will push the clamping plate 9 in the direction of the track. When the output end of the electric push rod 6 moves a distance L, the electric push rod 6 is closed. At this time, the clamping plates 9 on both sides of the track tightly clamp the track. It should be noted that the clamping ends of the clamping plates 9 are anti-slip treated to avoid slipping when clamping the track, and the clamping plates 9 are made of steel plates to meet the hardness requirements of the clamping plates 9. The electric push rod 6 in the electric clamping part can also be replaced with an electric slide rail or other electric driving components, using conventional settings.

[0032] The lifting assembly specifically includes a base 3, a lifting drive member and a mounting member. The base 3 is located below the U-shaped steel 1. Four lifting drive members are provided and are respectively installed at the four corners of the base 3. Four mounting members are provided and are respectively installed on both sides of the U-shaped steel 1. The four mounting members are respectively hinged to the driving ends of the four lifting drive members.

[0033] The lifting drive member may be an electric cylinder 4, the bottom end of which is fixed on the base 3, and the top end is hinged to the mounting member through a hinge, and the hinge is fixed to the mounting member and the electric cylinder 4 through bolts, or may be a lifting drive member such as a hydraulic cylinder or an electric lifting rod;

[0034] Before using the lifting assembly, fix the base 3 to the ground with screws. Take the electric cylinder 4 as an example. If the installation position of the track is on the same horizontal plane, all the electric cylinders 4 are powered on at the same time. The electric cylinder 4 will drive the installation part and the U-shaped steel 1 to move upward. When the track in the U-shaped steel 1 moves up to the required position, all the electric cylinders 4 are turned off. This operation makes it easy to install the track at the position of the required height.

[0035] If the installation position of the track has a certain height and angle, all the electric cylinders 4 are powered on at the same time, and the electric cylinders 4 will drive the installation parts and the U-shaped steel 1 to move upward together. When the lower end of the track reaches the installation position, the power of the electric cylinder 4 corresponding to the lower end of the track is turned off. If the high end of the track also reaches the installation position, the power of the electric cylinder 4 corresponding to the high end of the track is turned off. With the use of the lifting component and the electric clamping component, the track can be transported and clamped to the installation position at the required height and angle.

[0036] It should be noted that when the lifting drive component lifts the U-shaped steel 1, the mounting component will rotate at a certain angle on the U-shaped steel 1. The mounting component specifically includes a rotating block 2 and a rotating shaft 11. The rotating block 2 is sleeved and rotated on the rotating shaft 11, and the rotating block 2 is hinged to the top of the lifting drive component. The rotating shaft 11 is fixed to the outer wall of the U-shaped steel 1. When the lifting drive component drives the rotating block 2 to rise or fall and adjusts the angle of the U-shaped steel 1, the rotating block 2 will rotate on the rotating shaft 11 to meet the conditions for adjusting the height and angle of the U-shaped steel 1. A limiting portion is provided at the outer end of the rotating shaft 11 for limiting the rotating block 2 to prevent the rotating block 2 from slipping out from the outer end of the rotating shaft 11.

[0037] It also includes a control panel 5, which is installed on the U-shaped steel 1. The control panel 5 can be electrically connected to the power components in the device to enable the control panel 5 to control the power components in the device, making it easier and more labor-saving to use the device. Since the control panel 5 is connected to the mobile phone signal, the staff can remotely operate the control panel 5, making the operation of the device more convenient.

[0038] A number of evenly distributed limiting rollers 8 are installed on the top of the U-shaped steel 1. After the track enters the U-shaped steel 1, the bottom of the track contacts the transmission roller 7 and the top contacts the limiting roller 8, so that the track can be longitudinally limited in the U-shaped steel 1. During the track transmission process, the track will drive the limiting roller 8 to rotate on the top of the U-shaped steel 1.
