TECHNICAL FIELD
[0001] The utility model relates to the technical field of hydraulic engineering, and particularly relates to a hoist and draw machine alignment device. BACKGROUND
[0002] In the water conservancy and hydropower engineering, the mobile hoist and draw machine needs to run to the specified position of the dam orifice to open and close various steel gates. Usually, the ground personnel on the dam surface and the operating personnel in the hoist and draw machine repeatedly debug and position through the interphone to ensure that the hoist and draw machine runs to the specified position of the orifice. At least two personnel are needed to cooperate and operate, the labor cost is high, and a lot of time is wasted due to the need for repeated debugging and positioning. Especially when the number of gates and working conditions are more, the coordination workload is larger and there is a certain safety hazard. SUMMARY

[0006] The positioning support is arranged at the dam surface around the dam hole, and the mounting support with the sensing element is arranged on the hoist. When the hoist walks along the track on the dam, the hoist also drives the mounting support and the sensing element to move. Since the sensing direction of the sensing element is toward the plane where the positioning side of the positioning support is located, when the hoist carrying the sensing element does not move to the position aligned with the corresponding dam hole, the sensing element will not be directly opposite to the positioning side, and at this time, the sensing element will not sense the positioning side of the positioning support. Only when the hoist carrying the sensing element moves to be directly opposite to the positioning side, the sensing element will sense the positioning side of the positioning support. In other words, when the sensing element senses the positioning side of the positioning support, it indicates that the sensing element is directly opposite to the positioning side of the positioning support, and it also indicates that the hoist carrying the sensing element has walked to the position aligned with the corresponding dam hole. At this time, the operator in the driver's room of the hoist can control the hoist to stop, and then open and close the gate. Finally, the operator on the dam surface is not needed, and only the operator in the driver's room of the hoist can realize the alignment of the hoist and the dam hole. No repeated and multiple debugging is needed, a large amount of time is saved, the alignment efficiency is higher, and in addition, since the operator on the dam surface and the operator in the driver's room of the hoist do not need to cooperate, the danger of the operator on the dam surface can be avoided, and the safety is improved.
[0007] Further, the positioning support includes a positioning plate and a base plate which is connected with the positioning plate at an angle, and the base plate is arranged at the dam surface around the dam hole, wherein one plate surface of the positioning plate is the positioning side.
[0008] Further, the hoist alignment device further includes a fastener, the base plate is attached to the dam surface around the dam hole, and the fastener is used to fix the base plate at the dam surface around the dam hole.
[0009] Further, the fastener is an expansion bolt.
[0010] Further, the positioning support is an angle steel, and the positioning plate and the base plate are arranged perpendicularly.

[0013] Further, two nuts are sleeved on the sensing element, and the two nuts are respectively abutted against opposite sides of the second mounting plate.
[0014] Further, the inductive elements are provided with three, three of the inductive elements are sequentially distributed on the installation support along the walking direction of the hoist; the size of the positioning side along the walking direction of the hoist is a set size, and the spacing of the adjacent two inductive elements is greater than the set size.

[0021] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below with reference to the drawings.
[0022] In the description of the utility model, it is understood that the terms "upper", "lower", "left", "right", "front", "back" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.
[0023] Moreover, the Z-axis in the drawings represents the vertical direction, i.e., the up-down direction, and the positive direction of the Z-axis represents up and the negative direction of the Z-axis represents down; the Y-axis in the drawings represents the horizontal direction, i.e., the left-right direction, and the positive direction of the Y-axis represents left and the negative direction of the Y-axis represents right; and the X-axis in the drawings represents the longitudinal direction, i.e., the front-rear direction, and the positive direction of the X-axis represents front and the negative direction of the X-axis represents rear. It should be noted that the above-mentioned meanings of the Z-axis, the Y-axis and the X-axis are only for the convenience of describing the utility model and simplifying the description, and are not indicative or suggestive of the devices or elements referred to necessarily having a specific orientation, being constructed and operated in a specific orientation, and therefore should not be understood as limiting the utility model.
[0024] Referring to Figure 1 The utility model discloses an opening and closing machine alignment device, including positioning support 1, mounting bracket 2 and response element 3, positioning support 1 is used to set up at the dam surface of dam orifice periphery, one side of positioning support 1 is the positioning side 111, mounting bracket 2 is used to set up on opening and closing machine, response element 3 sets up on mounting bracket 2, and the response direction of response element 3 is towards the plane where positioning side 111 is at.
[0025] In the starting machine alignment device, positioning support 1 is set at the dam surface of the dam orifice periphery, and mounting bracket 2 with response element 3 is set on the opening and closing machine. When the opening and closing machine walks along the track on the dam, the opening and closing machine also drives mounting bracket 2 and response element 3 to move.
[0026] Since the response direction of response element 3 is towards the plane where the positioning side 111 of positioning support 1 is at, when the opening and closing machine with response element 3 does not move to the alignment position with the corresponding dam orifice, response element 3 will not face the positioning side 111, and at this time, response element 3 will not sense the positioning side 111 of positioning support 1. Only when the opening and closing machine with response element 3 moves to face the positioning side 111, response element 3 will sense the positioning side 111 of positioning support 1. In other words, when response element 3 senses the positioning side 111 of positioning support 1, it indicates that response element 3 faces the positioning side 111 of positioning support 1, and also indicates that the opening and closing machine with response element 3 has walked to the alignment position with the corresponding dam orifice. At this time, the operator in the driver's room of the opening and closing machine can control the opening and closing machine to stop, and then open and close the gate.
[0027] Finally, it can be ensured that the operator on the dam surface is not needed, but only the operator in the driver's room of the opening and closing machine can realize the alignment of the opening and closing machine with the dam orifice. Moreover, it is not needed to repeatedly and multiple times debug, a large amount of time is saved, and the alignment efficiency is higher. Furthermore, since the operator on the dam surface and the operator in the driver's room of the opening and closing machine do not need to cooperate, the danger of the operator on the dam surface can be avoided, and the safety is improved.
[0028] Need to explain, when the induction element 3 senses the positioning side 111 of the positioning support 1, the corresponding signal will be sent to the control platform of the hoist operator room, and then the operator in the hoist operator room knows.
[0029] Among them, as shown in Figure 1 The mounting bracket 2 can be fixed on the walking support of the hoist, and the walking direction of the hoist is the X-axis direction shown in the figure. The hoist can walk bidirectionally along the X-axis on the track, that is, the hoist can walk in the positive direction of the X-axis (the positive direction of the X-axis can be called the forward direction of the hoist), and also can walk in the negative direction of the X-axis (the negative direction of the X-axis can be called the backward direction of the hoist).
[0030] Unlike the walking direction of the hoist, the sensing direction of the induction element 3 is unidirectional. As shown in Figure 2 The positioning support 1 is located on the left side of the mounting bracket 2 and the induction element 3; the sensing direction of the induction element 3 is the unidirectional direction to the left (the positive direction of the Y-axis), and the induction element 3 cannot sense the structure (such as the hoist) on the right side.
[0031] Optionally, the induction element 3 is a proximity switch.
[0032] In this embodiment, the induction element 3 can be a proximity switch, which is a common induction device. First, its cost is low; second, the structure and principle of the proximity switch are relatively simple, easy to install and debug, and the operation is very simple, only need to connect the power supply and signal line; third, the detection speed of the proximity switch is generally fast, which can realize the response time of milliseconds, which is more conducive to accurate positioning of the hoist; fourth, most proximity switches are made of metal shell or high-temperature-resistant and corrosion-resistant materials, which can withstand large loads and harsh environments, and have long service life; fifth, the working voltage of the proximity switch is generally low, and the power consumption is also small, which saves energy; sixth, the proximity switch belongs to non-contact detection, which will not produce any mechanical interference or damage to the detected object (corresponding to the positioning support 1 of the utility model), and has high safety.
[0033] In this embodiment, when the sensing element 3 is a proximity switch, the working principle of the hoist alignment device is as follows: When the hoist carrying the proximity switch has not moved to align with the corresponding dam opening, the proximity switch will not be facing the positioning side 111, and at this time the proximity switch will not sense the positioning side 111 of the positioning bracket 1; only when the hoist carrying the proximity switch moves to face the positioning side 111 will the proximity switch sense the positioning side 111 of the positioning bracket 1. In other words, when the proximity switch senses the positioning side 111 of the positioning bracket 1, it indicates that the proximity switch is facing the positioning side 111 of the positioning bracket 1, and it also indicates that the hoist carrying the proximity switch has moved to the position aligned with the corresponding dam opening. At this time, the operator in the hoist driver's cab can control the hoist to stop and then open and close the gate.
[0034] It should be noted that when the sensing element 3 is a proximity switch, the sensing distance range of the proximity switch is generally 2-30cm, although this range may vary depending on the specific model of the switch. Therefore, after the positioning bracket 1 is installed on the dam surface around the dam opening, it is necessary to ensure that when the proximity switch is facing the positioning side 111 of the positioning bracket 1, the positioning side 111 of the positioning bracket 1 is within the sensing distance range of the proximity switch. In this way, when the proximity switch moves with the hoist to face the positioning side 111 of the positioning bracket 1, it can sense or detect the positioning side 111 of the positioning bracket 1.
[0035] In other embodiments, the sensing element 3 can also be a ranging sensor. In this case, the aforementioned sensing direction refers to the ranging direction of the ranging sensor (which is also a unidirectional direction). Thus, when the hoist carrying the ranging sensor has not moved to align with the corresponding dam opening, the ranging sensor will not be facing the positioning side 111. At this time, the ranging sensor will not detect its distance to the plane where the positioning side 111 is located (meaning it detects or senses the positioning side 111 of the positioning bracket 1). Only when the hoist carrying the ranging sensor moves to face the positioning side 111 will the ranging sensor detect its distance to the plane where the positioning side 111 is located. In other words, when the ranging sensor detects its distance to the plane where the positioning side 111 is located, it indicates that the ranging sensor is facing the positioning side 111 of the positioning bracket 1, and it also indicates that the hoist carrying the ranging sensor has moved to the position aligned with the corresponding dam opening. At this time, the operator in the hoist driver's cab can control the hoist to stop and then open or close the gate.
[0036] Optionally, such as Figure 1 As shown, the mounting bracket 2 is located at the bottom of the vehicle frame 6.
[0037] In this embodiment, the bottom of the walking frame 6 is the bottom position of the hoist, which is the position closest to the dam hole in the vertical direction and also the position closest to the positioning support 1 in the vertical direction. In this way, after the mounting support 2 with the sensing element 3 is arranged at the bottom of the walking frame 6, the height dimension of the positioning support 1 does not need to be high, and the top end of the positioning side surface 111 of the positioning support 1 can be ensured to be higher than the sensing element 3, so that after the hoist walks to the position, the sensing element 3 can face the positioning side surface 111 of the positioning support 1.
[0038] Optionally, as shown in Figure 2 The positioning support 1 includes a positioning plate 11 and a base plate 12 which is connected with the positioning plate 11 at an angle, and the base plate 12 is arranged at the dam surface of the periphery of the dam hole, wherein one plate surface of the positioning plate 11 is the positioning side surface 111.
[0039] In this embodiment, the positioning support 1 includes two parts, which are the positioning plate 11 and the base plate 12 connected at an angle, the base plate 12 is used to connect with the dam surface of the periphery of the dam hole, and one plate surface of the positioning plate 11 is used as the positioning side surface 111. Among them, the base plate 12 can be attached to the dam surface of the periphery of the dam hole, so as to increase the contact area of the positioning support 1 and the dam surface, so that the positioning support 1 is more stable after being fixed on the dam surface; the positioning plate 11 which is arranged at an angle with the base plate 12 is arranged at an angle with the dam surface, and the positioning side surface 111 of the positioning plate 11 is also arranged at an angle with the dam surface, so as to facilitate the sensing element 3 on the hoist to face the positioning side surface 111 of the positioning support 1.
[0040] Optionally, as shown in Figures 1-3 The hoist alignment device further includes a fastener 4, the base plate 12 is attached to the dam surface of the periphery of the dam hole, and the fastener 4 is used to fix the base plate 12 at the dam surface of the periphery of the dam hole.
[0041] In this embodiment, after the base plate 12 is attached to the dam surface of the periphery of the dam hole, the base plate 12 can be fixedly connected with the dam through the fastener 4. Among them, the base plate 12 with a certain plate surface area also provides space for the installation of the fastener 4.
[0042] Optionally, as shown in Figures 1-3 The fastener 4 is an expansion bolt.
[0043] In this embodiment, the fastener 4 can be an expansion bolt, which can avoid falling off after fixing the base plate 12 with the dam, and the connection effect is more stable.
[0044] In other embodiments, the fastener 4 can also be a common bolt, a rivet or other fastening structure.
[0045] Optionally, as shown in Figure 3As shown, the number of fasteners 4 is at least two.
[0046] In this embodiment, as shown in Figure 3 As shown, the number of fasteners 4 is at least two, and at least two fasteners 4 can be distributed on the base plate 12 in the walking direction of the hoist. The base plate 12 is fixedly connected to the dam at different positions by corresponding fasteners 4, and the connection effect is more stable, which can ensure that the horizontal distance from the different positions of the base plate 12 to the guide rail (on which the hoist walks) in the X-axis direction shown is stable and unchanging, thereby ensuring that the horizontal distance from the positioning side surface 111 at different positions in the X-axis to the guide rail is the same, and ensuring the accuracy of detection by the sensing element 3.
[0047] Optionally, as shown in Figures 1-2 The positioning bracket 1 is an angle steel, and the positioning plate 11 and the base plate 12 are vertically arranged.
[0048] In this embodiment, the positioning bracket 1 can be an angle steel, and the positioning plate 11 and the base plate 12 can be vertically arranged, which ensures that the positioning bracket 1 has high structural strength, and the angle steel is easy to obtain and does not need to be specially processed and produced, but only needs to have holes for the fasteners 4 to pass through. The number of angle steels can be determined according to the number of dam openings.
[0049] In other embodiments, the positioning bracket 1 can also be a channel steel or other structural members that are not easily damaged.
[0050] Optionally, as shown in Figures 1-2 The mounting bracket 2 includes a first mounting plate 21 and a second mounting plate 22 connected at an angle, the first mounting plate 21 is connected to the walking frame 6 of the hoist, and the second mounting plate 22 is provided with the sensing element 3.
[0051] In this embodiment, the mounting bracket 2 is used to be mounted on the walking frame 6 of the hoist through the first mounting plate 21, for example, the first mounting plate 21 is made of the same material as the walking frame 6 and can be welded and fixed; the second mounting plate 22 is used to mount the sensing element 3. Among them, the second mounting plate 22 is vertically arranged, and the first mounting plate 21 can be located at the top end of the second mounting plate 22, so that the first mounting plate 21 can provide certain shielding protection for the sensing element 3 on the second mounting plate 22.
[0052] Optionally, as shown in Figure 2 The second mounting plate 22 is provided with a through hole, and the sensing element 3 is arranged in the through hole.
[0053] In this embodiment, the second mounting plate 22 has a through hole, and the sensing element 3 is specifically inserted through the through hole and fixed relative to the second mounting plate 22. Thus, no additional support structure is needed; the second mounting plate 22 itself can support the sensing element 3. Furthermore, the sensing element 3 inserted through the through hole can be adjusted laterally to the positioning side 111 as needed, ensuring that the sensing element 3 can detect the positioning side 111 of the positioning bracket 1.
[0054] Optionally, such as Figure 2 As shown, the sensing element 3 is fitted with two nuts 5, which abut against the opposite sides of the second mounting plate 22 respectively.
[0055] In this embodiment, the sensing element 3 may have two nuts 5. After the sensing element 3 is inserted into the through hole, the two nuts 5 can be connected to the sensing element 3 respectively, and the two nuts 5 can be locked on both sides of the second mounting base to achieve relative fixation between the sensing element 3 and the second mounting plate 22. Furthermore, locking the relative position between the sensing element 3 and the second mounting plate 22 by the two nuts 5 also facilitates the adjustment of the position of the sensing element 3 relative to the second mounting plate 22, so as to adjust the lateral distance between the sensing element 3 and the positioning side 111 according to actual needs.
[0056] In other embodiments, the sensing element 3 and the second mounting plate 22 can also be fixed by snap-fitting, welding, screw connection, etc.
[0057] Optionally, such as Figure 1 and Figure 3 As shown, there are three sensing elements 3, which are distributed sequentially on the mounting bracket 2 along the traveling direction of the gate hoist; the dimension of the positioning side 111 along the traveling direction of the gate hoist is a set dimension, and the distance between two adjacent sensing elements 3 is greater than the set dimension.
[0058] In this embodiment, three sensing elements 3 are provided, and these three sensing elements 3 are distributed sequentially along the traveling direction of the hoist (X-axis direction in the figure). Along the negative X-axis direction, the three sensing elements 3 can be referred to as the first sensing element, the second sensing element, and the third sensing element, respectively. The three sensing elements 3 can ensure that the hoist can accurately position itself with the corresponding dam opening when moving forward and backward.
[0059] Specifically, in the working condition of the gate machine advancing (in the working condition of walking along the positive direction of the X axis), the gate machine can advance at a faster speed, and when the first sensing element moves to the positioning side surface 111 of the positioning support 1, the operator in the driver's room of the gate machine can control the gate machine to decelerate; when the first sensing element passes the positioning side surface 111 and the second sensing element is opposite to the positioning side surface 111, the operator in the driver's room of the gate machine can control the already decelerated gate machine to stop, so that the accurate positioning of the gate machine is realized.
[0060] Similarly, in the working condition of the gate machine retreating (in the working condition of walking along the negative direction of the X axis), the gate machine can retreat at a faster speed, and when the third sensing element moves to the positioning side surface 111 of the positioning support 1, the operator in the driver's room of the gate machine can control the gate machine to decelerate; when the third sensing element passes the positioning side surface 111 and the second sensing element is opposite to the positioning side surface 111, the operator in the driver's room of the gate machine can control the already decelerated gate machine to stop, so that the accurate positioning of the gate machine is realized.
[0061] In summary, the gate machine alignment device has at least the following effects: low manufacturing cost, not easy to be damaged, fast response speed, strong adaptability, single-person operation for debugging and positioning of the gate machine, and reduced safety risk.
[0062] The terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include at least one of the features.
[0063] Although the utility model discloses as above, the protection scope of the utility model is not limited to this. The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will all fall into the protection scope of the utility model.
