[0001] The utility model relates to the technical field of stamping work tickets and operation tickets of a hydropower station, in particular to a stamping mechanism and a stamping auxiliary device for the work tickets and operation tickets of a hydropower station. Background Art

[0002] There are six types of stamps on work tickets and operation tickets in hydropower stations: "Canceled", "Expired", "Blank Below", "Not Executed", "Executed" and "Invalid". Each time a work ticket is cancelled or an operation ticket is executed, one or more of the above stamps must be stamped in the designated area according to the actual situation. The stamping position of each work ticket is relatively fixed, and needs to be stamped in a smaller range in the upper right corner. The last operation ticket needs to be stamped with a "Blank Above" stamp in an uncertain position and other seals in relatively fixed positions. The stamping position of each other operation ticket is also relatively fixed, and needs to be stamped in a smaller range in the upper right corner, and the seal cannot be stamped on the words, otherwise it will affect the validity of the work ticket and operation ticket.

[0003] The existing stamping method is that the staff directly selects the appropriate stamp and stamps it on the corresponding position after visual identification. When the staff cancels the work tickets collectively or sorts out the work tickets after performing multiple operations in succession, they may have problems such as inaccurate stamping position and unclear seals due to lack of concentration and unskilled operation, thereby affecting the validity of the work tickets and operation tickets. It can be seen that there is currently a lack of an auxiliary device to improve the accuracy and work efficiency of the staff's long-term stamping. In addition, during the existing stamping process or during the intervals of stamping work, paper may run around.

[0004] Therefore, it is urgent to propose a stamping mechanism and a stamping auxiliary device for a hydropower station work ticket and an operation ticket. Utility Model Content

[0044] Example 1

[0045] Reference Figures 1-2 The first embodiment of the utility model provides a stamping mechanism, including a positioning component 100, which includes a pressing plate 101, a sliding groove 102 opened on the inner side of the pressing plate 101, and a positioning slider 103 slidably arranged in the sliding groove 102; wherein, the upper and lower surfaces of the pressing plate 101 are both flatly arranged to facilitate flattening work tickets or operation tickets, the sliding groove 102 is arranged along the length direction of the pressing plate 101, and the positioning slider 103 can slide in the length direction of the pressing plate 101.

[0046] Furthermore, the stamping mechanism also includes a locking assembly 200 capable of locking the positioning slider 103 at a specific position in the sliding groove 102, which includes an elastic clip 201 fixedly connected to the positioning slider 103, and a locking groove 202 opened on the pressure plate 101 away from the side of the work ticket or the operation ticket; wherein the elastic clip 201 is in contact with the locking groove 202, and the elastic clip 201 can be clamped in the locking groove 202.

[0047] Operation process: first place the pressing plate 101 horizontally on the work ticket or operation ticket, and at the same height as the position where the stamp is required on the work ticket or operation ticket, and then control the positioning slider 103 to slide in the sliding groove 102 according to the position where the stamp is required, until the positioning slider 103 slides to the appropriate horizontal coordinate, and then stamp the corresponding seal in the positioning slider 103; when the stamp position of the next ticket remains unchanged, the staff only needs to lift the pressing plate 101 gently, and then remove the stamped work ticket or operation ticket from under the pressing plate 101. When the stamp position and quantity of the next ticket change, adjust the position of the pressing plate 101 and the positioning slider 103 as needed. The weight of the pressing plate 101 itself is not very heavy, but it can press the work ticket or operation ticket tightly to prevent them from running off or flying around.

[0048] Example 2

[0049] Reference Figures 2 to 4 This embodiment is different from the first embodiment in that: the pressing plate 101 includes a pressing block 101a, two pressing blocks 101a are provided and the two pressing blocks 101a are arranged in parallel on the upper and lower sides of the pressing plate 101, the pressing blocks 101a are both long strips, and the upper and lower surfaces of the pressing blocks 101a are both flat, which is convenient for flattening the work ticket or the operation ticket; the positioning slider 103 does not protrude from the surface of the pressing plate 101 in the thickness direction, so as to prevent the positioning slider 103 from scratching the surface of the work ticket or the operation ticket during the sliding process in the sliding groove 102.

[0050] Specifically, a hollow groove 103a is opened on the inner side of the positioning slider 103. Both the positioning slider 103 and the hollow groove 103a are rectangular. The hollow groove 103a is the position for stamping. The hollow groove 103a further limits the position of stamping and further accurately determines the position of stamping. Moreover, the shape of the hollow groove 103a matches the shape of the stamp.

[0051] A guide groove 101a-1 is provided on one side opposite to the two pressing blocks 101a, and the two guide grooves 101a-1 are parallel to each other. Limit blocks 103b are fixedly arranged on the upper and lower sides of the positioning slider 103; the limit blocks 103b are slidably arranged in the guide groove 101a-1, and the two guide grooves 101a-1 are respectively located on the upper and lower sides of the sliding groove 102. The positioning slider 103 can slide horizontally in the sliding groove 102 through the cooperation of the limit blocks 103b and the guide groove 101a-1, and the cooperation between the guide groove 101a-1 and the limit blocks 103b can also prevent the positioning slider 103 from falling off the pressure plate 101.

[0052] Furthermore, connecting block 101b and connecting block 101c are fixedly provided on the left and right sides of the pressing block 101a respectively, and the opposite sides of connecting block 101b and connecting block 101c are parallel to each other. Connecting block 101b and connecting block 101c are connected to the upper and lower pressing blocks 101a. The two pressing blocks 101a, connecting block 101b and connecting block 101c together form a sliding groove 102, and the sliding groove 102 is also rectangular.

[0053] The locking groove 202 is composed of a plurality of tooth grooves distributed side by side. The elastic clip 201 is in a "U" shape. The elastic clip 201 itself is elastic. One end of the elastic clip 201 is fixedly connected to the positioning slider 103 , and the other end of the elastic clip 201 is embedded in the locking groove 202 .

[0054] The rest of the structure is the same as that of Example 1.

[0055] Operation process: Normally, the elastic clip 201 is embedded in the locking groove 202 to lock the position of the positioning slider 103. When the position of the positioning slider 103 needs to be changed, the elastic clip 201 is pulled to make it leave the locking groove 202, and then the positioning slider 103 is moved to the required position, and then the elastic clip 201 is lowered to make it bounce back into the locking groove 202 at the corresponding position to lock the position of the positioning slider 103.

[0056] Example 3

[0057] Reference Figure 1 and Figures 5-6 This embodiment is different from the first embodiment in that: when the same seal is stamped on multiple work tickets or operation tickets, it is troublesome to repeatedly pick up the seal, stamp it and then take it out each time. This embodiment is provided with a clamping assembly 300 that can quickly clamp the seal on the positioning slider 103, and can also quickly take out the clamping assembly 300, which further provides convenience for the operator, and the clamping assembly will not block the locking assembly 200 and the hollow groove 103a, and will not affect the activity of the locking assembly 200.

[0058] Specifically, the clamping portion 301 includes a connecting seat 301a fixedly arranged on the same side of the positioning slider 103 as the locking assembly 200, two connecting blocks 301b fixedly arranged on the upper and lower sides of the connecting seat 301a away from the positioning slider 103, a fixing plate 301c fixedly arranged on the two connecting blocks 301b, two sliding blocks 301d fixedly arranged on the fixing plate 301c close to the positioning slider 103, and two clamping blocks 301e slidably arranged on the two sliding blocks 301d, each of which has a limited opening. The sliding block 301d is slidably arranged in the limiting groove 301f, and a protrusion is arranged on the side of the sliding block 301d away from the fixed plate 301c. The protrusion is arranged to prevent the clamping block 301e from falling off the limiting block 103b and to prevent the clamping block 301e from moving axially in the limiting block 103b. The connecting seat 301a is in an inverted "C" shape, and the two connecting blocks 301b are arranged on the upper and lower sides of the connecting seat 301a. The clamping block 301e is provided with a recess for the connecting block 301b to pass through without affecting the activity of the clamping block 301e itself.

[0059] Furthermore, the control unit 302 includes a second fixing plate 302a fixedly arranged on the connecting seat 301a on the same side as the connecting block 301b, two connecting rods 302b fixedly arranged on the second fixing plate 302a away from the side of the hollow groove 103a, a control plate 302d slidably arranged on the circumferential surfaces of the two connecting rods 302b, two springs 302c fixedly arranged between the control plate 302d and the second fixing plate 302a, and two connecting columns 302e arranged between the control plate 302d and the clamping block 301e, the two springs 302c are respectively sleeved on the circumferential surfaces of the two connecting rods 302b, the two connecting columns 302e are respectively fixedly arranged on the right ends of the two clamping blocks 301e, the two connecting columns 302e are respectively rotatably connected to the two ends of the control plate 302d, and the end of the connecting rod 302b away from the spring 302c is provided with a protrusion to prevent the control plate 302d from falling off the connecting rod 302b.

[0060] Reference Figure 5, viewed from a direction perpendicular to the hollow groove 103a, the left ends of the two clamping blocks 301e on the opposite sides are both provided with a protrusion 301e-1, and the side of the protrusion 301e-1 close to the hollow groove 103a is fixedly provided with an elastic pad 1 302f, and the right ends of the clamping blocks 301e are movably connected to the control board 302d, and the side of the fixed plate 302a close to the hollow groove 103a is fixedly provided with an elastic pad 2 302g, and the two clamping blocks 301e and the fixed plate 302a are both ... Plate 1 301c together encloses the area through which the seal passes. The setting of elastic pad 1 302f and elastic pad 2 302g can not only prevent the clamping assembly 300 from damaging the surface of the seal, but also enhance the friction between the seal and the protrusion 301e-1, and the seal and the fixed plate 1 301c; the two limit grooves 301f are both inclined, the upper limit groove 301f is set higher on the left and lower on the right, and the lower limit groove 301f is mirror-symmetrical with the upper limit groove 301f.

[0061] Normally, the sliding blocks 301d are located at the left end of the corresponding limiting grooves 301f, and the springs 302c are in a compressed state, pushing the control plate 302d to the right. Due to the protrusion at the right end of the connecting rod 302b, the control plate 302d cannot be pushed further to the right, and the protrusion 301e-1 at the left end of the clamping block 301e enters a very small distance into the space in the normal direction of the hollow groove 103a; pressing the control plate 302d in the direction close to the spring 302c, the control plate 302d can drive the clamping block 301e to move to the left through the connecting column 302e. Due to the inclined setting of the limiting grooves 301f, the left sides of the two clamping blocks 301e move to the left and move away from each other.

[0062] When the seal needs to be installed, first press the control plate 302d in the direction close to the spring 302c, then place the bottom of the seal facing the hollow groove 103a, between the clamping block 301e and the second fixed plate 302a, and then release the control plate 302d, and the clamping assembly 300 can clamp the seal; when the seal needs to be removed, press the control plate 302d in the direction close to the spring 302c, and then take out the seal.
