The problem with quick clamping is that the web of the rail will be deviated, and sometimes the rail cannot be clamped tightly, and the knob needs to be adjusted to achieve the purpose of clamping the rail. The traditional screw jacking device generally rotates the clamping screw by pulling the clamping handle rod to press the clamping wheel. There is a problem that the screw needs to be rotated many times to clamp the rail each time, resulting in difficulty in quickly completing the rail clamping work, thereby reducing the efficiency of railway emergency repair work. In view of the above defects, this application is proposed. Content of the Utility Model

The embodiments described below are only examples, and those skilled in the art can think of other obvious deformations. The basic principles defined in the following description of the present utility model can be applied to other implementation schemes, deformation schemes, improvement schemes, equivalent schemes, and other schemes that do not depart from the spirit and scope of the present utility model.

[0021]

Embodiment 1

[0022] A rail clamping device, such as Figure 1 , includes a main body, a clamping positioning plate 011, a clamping support plate 008, and an operating component.

[0023] In this embodiment, the main body adopts a U-shaped plate 004, which has relatively high strength. Two groups of clamping positioning plates 011 are provided and are both installed on the U-shaped plate 004. Through holes for the drill bit of the drilling machine to pass through are provided on the U-shaped plate 004.

[0024] The clamping support plate 008 is composed of two plates. The two plates are fixed through a support limit pin 013 and a support reinforcement pin 009. The two plates not only improve the overall strength of the clamping support plate 008, but also increase the width of the clamping support plate 008 to ensure the stability of clamping.

[0025] The clamping support plate 008 is rotatably installed between the clamping positioning plates 011 through a support movable pin 010. A positioning groove and a rail clamping portion are provided on the clamping support plate 008. The rail clamping portion can be integrally formed at the lower end position of the clamping support plate 008, or can be realized by installing other components. In this embodiment, the rail clamping portion includes clamping pieces 007 installed on the clamping support plate 008. The clamping pieces 007 are circular, and two groups of clamping pieces 007 are provided and are respectively arranged on both sides of the clamping support plate 008.

[0026] Rail abutting plates 005 are respectively installed on both sides of the U-shaped plate 004. When clamping the rail, the rail abutting plate 005 and the rail clamping portion are respectively located on both sides of the rail. The front side of the rail abutting plate 005 has two inclined surfaces, which can maintain a better contact effect with the rail when clamping the rail.

[0027] A handle fixing block 003 is installed on the U-shaped plate 004. The handle vertical pipe 002 is installed at the handle fixing block 003, and can be fixedly connected or movably connected, such as threaded connection, which is convenient for disassembly. The handle assembly 001 is installed on the handle vertical pipe 002. The U-shaped plate 004 can be connected to the main body of the drilling machine. When in use, the drilling machine is lifted by using the handle assembly 001.

[0028] The operating component includes a support fixing nut 012, a support screw 015, and a support movable nut 014.

[0029] A handle rod 016 is installed on the support screw rod 015 for easy operation, and handle rod bakelite balls 017 are installed at both ends of the handle rod 016.

[0030] The support movable nut 014 is installed on the positioning groove. The positioning groove is an arc-shaped groove, which can be a through groove or a blind groove. The lower end of the arc-shaped groove is the clamping end, and the upper end is the relaxation end. The support movable nut 014 can move in the positioning groove. The support screw rod 015 is threadedly connected to the support movable nut 014. The end of the support screw rod 015 is preferably provided with a cylindrical thick head with a diameter larger than that of the support screw rod 015. The position where the support fixed nut 012 contacts the support screw rod 015 is preferably provided as a quadrangular prism, so that the cylindrical thick head abuts against one side plane of the quadrangular prism, facilitating stable contact with the support fixed nut 012. The support fixed nut 012 is installed on the clamping and positioning plate 011, and in other embodiments, it can also be installed at other positions such as the U-shaped plate 004.

[0031] In other embodiments, it is not limited to using an arc-shaped groove, and a broken line-shaped groove or the like can also be used as long as it can achieve the effect of making the clamping support plate 008 rotate when the support movable nut 014 moves in the positioning groove.

[0032] By using the two extreme positions of the support fixed nut 012 and the support movable nut 014 and connecting through the slot of the clamping support plate 008, the two states of clamping and loosening can be quickly achieved.

[0033] Operation of clamping the rail: Such as Figure 3 、 Figure 4 , by pressing down the handle rod 016, the support movable nut 014 moves to the clamping end of the positioning groove, making the end of the support screw rod 015 tightly press against the support fixed nut 12. At the same time, the clamping support plate 008 rotates, so as to press the rail tightly by using the rail clamping piece 007. This clamping method has the convenient effect of a traditional quick clamp. The rail structure refers to Figure 2 , if it is not completely pressed at this time, the handle rod 016 can be rotated to make the support screw rod 015 further tightly press against the support fixed nut 12 to achieve the purpose of complete pressing. This step combines the advantage of easy adjustment of the traditional screw tightening, and at the same time, due to the combination of the quick clamp step, it is not necessary to rotate the screw for many turns to achieve the complete clamping effect.

[0034] Operation of loosening the rail: By rotating the handle rod 016, when the support screw rod 015 no longer tightly presses against the support fixed nut 012, pull up the handle rod 016, and the support movable nut 014 moves to the relaxation end of the positioning groove, so as to loosen the rail clamping piece 007 and achieve the purpose of quickly derailing the rail.

[0035] Through the above structure, by adopting the combination of quick clamping and screw jacking, the purpose of quickly clamping the rail can be achieved. During the drilling operation of the drilling machine, the rail clamping work can be quickly completed within a short time, saving time for railway emergency repair work.

[0036] Embodiment 2: On the basis of Embodiment 1, a slide rail seat 006 is installed on the U-shaped plate 004. The slide rail seat 006 and the U-shaped plate 004 are connected together by welding or other connection methods, providing an installation position for the clamping and positioning plate 011. The slide rail seat 006 has a cavity for the guide block of the drill bit clamping position of the drilling machine to extend into, playing a role of a sliding guide track for the adjustment of the drilling position.

[0037] A drilling machine includes the above rail clamping device.

[0038] Those skilled in the art should understand that the above description and the embodiments of the present invention shown in the drawings are only examples and do not limit the present invention. The purpose of the present invention has been completely and effectively achieved. The function and structural principle of the present invention have been shown and described in the embodiments. Without departing from the above principle, the embodiments of the present invention can have any deformation and modification.
