[0002] The gate hoist, also known as the hoist gate, is a large-scale hydraulic machinery product. The gate hoist is related to the normal operation of hydraulic structures. In addition to meeting the design requirements of general lifting machinery, it is of special significance to work safely and reliably and to operate flexibly and conveniently.

[0003] The gate hoist needs to be equipped with a protective measuring device when in use. However, when installing the existing protective measuring device, it is necessary to drill holes on the gate hoist support frame and then connect them with bolts. On the one hand, the drilling method is time-consuming and labor-intensive, increasing the workload of workers, and on the other hand, it also reduces the structural strength of the gate hoist support frame. Utility Model Content

[0007] The width of the gap is greater than the width of the stud portion of the bolt 1 and less than the width of the nut portion of the fastening bolt 1.

[0008] The connecting through groove is a strip groove structure, and the width of the connecting through groove is greater than the width of the stud portion of the fastening bolt II and less than the width of the nut portion of the fastening bolt II.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 3 As shown, the utility model provides a connection frame for punch-free installation, including an N-shaped bracket portion 81 and a horizontal plate portion 82 constructed below the bracket portion 81, a connecting through groove 85 is opened on the top of the bracket portion 81, which is used to be fixedly connected to a bidirectional measuring device through a fastening bolt II87, two groups of the horizontal plate portions 82 extend along the inner side of the bracket portion 81, and a gap is left between the two groups of the horizontal plate portions 82;

[0026] The fastening bolt I83 is a fastener used in the prior art to fix the cover plate 91 of the gate opening and closing machine. It is an inherent structure on the gate opening and closing machine. When the connecting frame needs to be connected to the gate opening and closing machine, firstly reversely screw one of the fastening bolts I83 on the cover plate 91 so that the stud portion of the fastening bolt I83 is exposed outside the cover plate 91, and then the stud portion of the fastening bolt I83 is inserted in the radial direction through the gap 84 between the two groups of the transverse plate portions 82 on the connecting frame, and then the wrench is inserted into the inner side of the connecting frame and the fastening bolt I83 is screwed in the forward direction so that the stud portion of the fastening bolt I83 gradually enters the cover plate 91, and then the nut of the fastening bolt I83 moves in the direction close to the transverse plate portion 82 until it is tightly against the transverse plate portion 82 near the gap 84, thereby realizing the fixed connection between the connecting frame and the gate opening and closing machine.

[0027] Specifically, the width of the gap 84 is greater than the width of the stud portion of the bolt 183 and less than the width of the nut portion of the fastening bolt 183.

[0028] Specifically, the connecting slot 85 is a strip slot structure, and the length extension direction of the connecting slot 85 is consistent with the length extension direction of the gap, so that the position of the bidirectional measuring device on the connecting frame can be adjusted according to the volume of the bidirectional measuring device, that is, the relative position of the bidirectional measuring device and the gate hoist can be adjusted;

[0029] Specifically, the width of the connecting slot 85 is greater than the width of the stud portion of the fastening bolt II87 and less than the width of the nut portion of the fastening bolt II87, so that the bidirectional measuring device and the connecting frame can be fixed by screwing the fastening bolt II87.

[0030] Specifically, both side ends of the bracket portion 81 are provided with working grooves 86. The design of the working grooves 86 allows a wrench to enter from both side ends of the bracket portion 81 to the inner side of the bracket portion 81 to tighten the bolts I83, thereby increasing the working space of the wrench.

[0031] Furthermore, the present application also provides a bidirectional measuring device, including a connecting frame that can be installed without punching. A threaded hole is provided at the bottom of the base 5 of the bidirectional measuring device, and the stud portion of the fastening bolt II87 passes through the connecting groove 85 and is threadedly connected to the base 5; by providing a threaded hole at the bottom of the base 5, the fixation of the bidirectional measuring device and the connecting frame is achieved.

[0032] Furthermore, considering that the protection measuring device needs to have a gate position measurement function (the movement between the starting position and the end position can provide position data in real time) or a stroke measurement function (position data is provided only when the starting position or the end position is reached) to avoid the gate being blocked by foreign objects and unable to move during the lifting process while the motor is still outputting continuously; however, most of the existing corresponding protection measuring devices for gate hoists are unidirectional, that is, they can only measure the gate position or the stroke; and the existing stroke measurement requires two limit switches to be installed at the highest point and the lowest point of the actual lifting respectively, which is very inconvenient for disassembly and maintenance, and there are also safety hazards;

[0033] In view of the technical problems existing in the above-mentioned protection measuring device, the bidirectional measuring device in the present application is also designed with a transmission mechanism and a tensioning mechanism;

[0034] like Figures 3 to 6 As shown, specifically, the transmission mechanism includes a transmission gear 21 and a limit measuring seat 22. The transmission gear 21 is connected to the limit measuring seat 22 through a transmission shaft 23. When the transmission gear 21 is connected to a driving source component that is started synchronously with the gate, the limit measuring seat 22 can be driven to move back and forth between the travel switch groups 3. When the gate reaches the highest or lowest limit position, the limit measuring seat 22 also synchronously contacts the travel switch group 3, thereby triggering the upper limit switch or the lower limit switch of the travel switch group 3 to achieve travel measurement.

[0035] The tensioning mechanism includes a movable arm 11 and an elastic member 12 hooked and connected to the movable arm 11. The transmission gear 21 is coaxially connected to the encoder 4 on the movable arm 11. As the transmission gear 21 rotates, the encoder 4 also counts synchronously, thereby realizing gate position measurement. The elastic member 12 is used to drive the movable arm 11 to move in a direction close to the driving source component, so that the transmission gear 21 is tightly meshed with the driving source component. When the installation position of the driving source component is offset, it plays a role in position compensation;

[0036] The gate hoist adopts screw type opening and closing, and the driving source is the lifting screw 6, which is meshed and connected with the transmission gear 21;

[0037] Compared with the prior art, the bidirectional measuring device has the functions of stroke measurement and gate position measurement at the same time, and can collect and compare the data of stroke measurement and gate position measurement to achieve the safety guarantee of dual mechanical counting measurement. It can also compare and analyze the data of stroke measurement and gate position measurement with the data of the voltage overload protection system of the gate hoist, thereby increasing the safety of the gate hoist;

[0038] The transmission mechanism is creatively used to proportionally scale the actual lifting height of the gate, so that the upper limit switch and the lower limit switch do not need to be installed at the actual lifting height position, and the stroke measurement can also be achieved.

[0039] Specifically, the encoder 4 is fixedly installed horizontally on the movable arm 11, and its output end passes through the movable arm 11 and is coaxially fixedly connected to the transmission gear 21. When the transmission gear 21 rotates, the encoder 4 counts synchronously and measures the actual height position of the gate in real time.

[0040] Specifically, the transmission gear 21 is a double-layer tooth structure, wherein the outer large teeth are used for meshing connection with the driving source component, and the inner small teeth are meshed connection with the secondary gear 24 coaxial with the transmission shaft 23 .

[0041] In this technical solution, two solutions are designed to drive the limit measuring seat 22 to move; wherein, the first solution is that the transmission shaft 23 and the limit measuring seat 22 are started synchronously, and the second solution is that the transmission shaft 23 and the limit measuring seat 22 are started asynchronously;

[0042] like Figures 5 to 7As shown, in scheme one, the transmission shaft 23 is a screw structure, which is installed on the base 5 through a seat bearing, the limit measuring seat 22 is a corresponding screw nut structure or is installed on the screw nut, the upper limit switch and the lower limit switch of the travel switch group 3 are diagonally installed on the sides of the starting end and the end of the travel of the two groups of limit measuring seats 22, and the two groups of limit measuring seats 22 are installed front and back on the transmission shaft 23 of the screw structure; when the gate reaches the limit position of the highest point, one group of limit measuring seats 22 touches the upper limit switch to achieve the highest point measurement, when the gate descends, the transmission shaft 23 reverses synchronously, when the gate reaches the limit position of the lowest point, the other group of limit measuring seats 22 touches the lower limit switch to achieve the lowest point measurement.

[0043] like Figures 7 and 8 As shown in the second scheme, a transmission sleeve 29 is fixedly mounted on the transmission shaft 23, and the outer large teeth of the transmission gear 21 are of a semi-tooth structure, that is, the entire circumferential surface of the outer large teeth has only partial teeth, thereby intermittently driving the secondary gear 24 coaxially connected to the transmission shaft 23 to rotate, and at least two groups of annular grooves 25 are constructed on the outer circumferential surface of the transmission sleeve 29, and a delayed reversing smooth rod 26 is slidably connected in the annular groove 25, and the delayed reversing smooth rod 26 is connected to the limit measuring seat 22, and openings 253 connected to the annular groove 25 are opened on both axial end surfaces of the transmission sleeve 29 for the entry and exit of the delayed reversing smooth rod 26, and the annular groove 25 includes a straight thread groove section 251 and an oblique thread groove section 252. The thread groove section 252, the straight thread groove section 251 is coaxially arranged with the transmission sleeve 29, the oblique thread groove section 252 is designed as an oblique spiral on the outer periphery of the transmission sleeve 29, the opening 253 is constructed on the oblique thread groove section 252, one end of the reversing plate 27 is arranged facing the annular groove 25, and is installed on the seat bearing 28, thereby realizing the rotation of the reversing plate 27, the delayed reversing smooth rod 26 is vertically installed on the reversing plate 27 and arranged in a circle on the reversing plate 27, one group of the delayed reversing smooth rods 26 is connected to the limit measuring seat 22, and the upper limit switch and the lower limit switch of the travel switch group 3 are installed on the moving path of the delayed reversing smooth rod 26;

[0044] When the transmission sleeve 29 rotates, if the delayed reversing smooth rod 26 is in the straight thread groove section 251, the transmission sleeve 29 continues to idle relative to the delayed reversing smooth rod 26, so that the delayed reversing smooth rod 26 maintains the current position state. When the delayed reversing smooth rod 26 is in the oblique thread groove section 252, under the pushing action of the oblique thread groove section 252, the delayed reversing smooth rod 26 is offset along the extension direction of the oblique thread groove section 252 and moves out from the outlet. At the same time, an adjacent group of delayed reversing smooth rods 26 enters the transmission sleeve 29 from the entrance and repeats the above action, thereby the limit measuring seat 22 is asynchronously and intermittently started relative to the transmission shaft 23. When the gate reaches the upper limit position or the lower limit position, the delayed reversing smooth rod 26 connected to the limit measuring seat 22 touches the upper limit switch or the lower limit switch on the moving path, thereby realizing the stroke measurement.

[0045] Compared with the design of Scheme 1, the design of Scheme 2 can reduce the overall length of the bidirectional measuring device and is suitable for working conditions with limited installation length and position.

[0046] like Figure 3 As shown, specifically, the movable arm 11 is rotatably connected to the base 5, the elastic member 12 is a double-headed tension spring, the other end of which is hooked on the base 5, and a plurality of hanging holes 51 corresponding to the elastic member 12 are sequentially opened along the height direction of the movable arm 11, and the pressing elastic force when the transmission gear 21 is meshed with the driving source member can be adjusted by hooking the hanging holes 51 at different height positions.

[0047] Specifically, the movable arm 11 is also provided with a transverse strip waist groove (not shown in the figure), and a plurality of threaded holes are provided on the base 5 along the extension direction of the transverse strip waist groove. The position of the movable arm 11 can be adjusted by screws (not shown in the figure) passing through the transverse strip waist groove and then connecting the threaded holes at different positions. The movable arm 11 is suitable for use in working environments with limited installation width and position.

[0048] Specifically, the bidirectional measuring device further includes an outer protective cover shell made of metal material, and the outer protective cover shell is buckled and connected to the base 5 .

[0049] like Figure 3 As shown, further, in the present application, a gate opening and closing machine is also proposed. The gate opening and closing machine is a screw-type opening and closing machine, and the lifting screw 6 of the gate opening and closing machine is meshed and connected with the transmission gear 21 of the bidirectional measuring device.

[0050] The working principle and working process of the utility model are as follows:

[0051] When the gate opening and closing machine is started, the lifting screw 6 of the gate opening and closing machine synchronously drives the transmission gear 21 to rotate, and the encoder 4 coaxially connected to the transmission gear 21 counts synchronously with the rotation of the transmission gear 21, and measures the actual height position of the gate in real time. At the same time, the transmission gear 21 also drives the transmission shaft 23 to rotate through the secondary gear 24 coaxially connected to the transmission shaft 23. During the rotation of the transmission shaft 23 of the screw rod structure, the limit measuring seat 22 of the screw rod nut structure or the limit measuring seat 22 installed on the screw rod nut moves synchronously along the transmission shaft 23. When the gate reaches the limit position of the highest point, one group of the limit measuring seats 22 touches the upper limit switch to realize the highest point measurement. When the gate descends, the transmission shaft 23 reverses synchronously. When the gate reaches the limit position of the lowest point, another group of the limit measuring seats 22 touches the lower limit switch to realize the lowest point measurement, thereby realizing the function of stroke measurement.

[0052] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the utility model should still fall within the scope of this patent.
