Description

Technical Field

[0001] This utility model relates to the field of quay crane track construction technology, and in particular to a positioning frame for pre-embedded bolts on steel pads of quay crane tracks. Background Technology

[0002] A quay crane, formally known as a quay container crane, is a heavy-duty crane designed specifically for container terminals to load and unload cargo from container ships. These cranes are typically deployed along the edge of port terminals. The bottom of the quay crane is equipped with rollers that move along steel rails laid on the quay structure, allowing the crane to be flexibly positioned along the length of the quay. The rails are securely embedded in track grooves within the quay superstructure and supported and secured by a series of continuously laid steel plates. Each steel plate is fixed to the bottom of the track groove by pre-embedded bolts within the groove.

[0003] The core function of steel rail pads is to maintain the stable position of the rails, effectively preventing lateral or longitudinal displacement when subjected to dynamic loads and preserving the geometric accuracy of the rails. Furthermore, steel rail pads can evenly distribute the pressure on the rails to the foundation, avoiding stress concentration and reducing the risk of deformation or cracking of the rails and ground due to excessive pressure.

[0004] Since each steel pad needs to be precisely aligned with multiple pre-embedded bolts, the accurate positioning of these bolts before the track trough concrete is poured is extremely critical. Any deviation in the position of the pre-embedded bolts, or inaccurate control of their distances, will directly prevent the steel pads from being installed smoothly, leading to delays and costly rework. However, in traditional pre-embedding methods, to ensure the accuracy of the bolt placement, each pre-embedded bolt needs to be individually calibrated and fixed, resulting in low efficiency during the installation process. Utility Model Content

[0005] The purpose of this utility model is to overcome the problem of low efficiency in the embedding process of pre-embedded bolts for track steel pads in the existing technology, and to provide a positioning frame for pre-embedded bolts of track steel pads for quay cranes.

[0006] This utility model provides a positioning frame for pre-embedded bolts on the steel pad plate of a quay crane track, comprising:

[0007] The positioning frame includes multiple longitudinal components and connectors arranged side by side. The multiple longitudinal components are provided with positioning holes. The number and position of the positioning holes match the number and position of the pre-reserved screw holes on the steel pad. The positioning holes are used to pass through the pre-embedded bolts and can be connected to the top of the pre-embedded bolts. The multiple longitudinal components are connected to each other through the connectors.

[0008] A fixing frame is used to connect the positioning frame body to the reinforcing bars of the track groove.

[0009] This utility model provides a positioning frame for pre-embedded bolts on the steel pad plate of a quay crane track. The connecting member is used to connect multiple longitudinal components into a whole, thereby fixing the relative positions of the various longitudinal components. The fixing frame is used to fix the positioning frame body in a predetermined position before pouring the track groove, avoiding unnecessary displacement of the positioning frame body during the pouring process, thus ensuring the accuracy of the position of the pre-embedded bolts. The number and position of the positioning holes match the number and position of the reserved screw holes on the steel pad plate, ensuring that all pre-embedded bolts matching the steel pad plate can be pre-embedded and installed through the positioning frame body. By temporarily fixing the pre-embedded bolts in the positioning holes, and utilizing the fixed relative positions of the positioning holes on the positioning frame body, it can be ensured that all temporarily fixed pre-embedded bolts also maintain a fixed relative position.

[0010] During installation, once the overall position of the positioning frame is determined, the position of the pre-embedded bolts is also determined, eliminating the need to position and fix each pre-embedded bolt individually as in traditional methods. Using the positioning frame, the pre-embedded bolts can be conveniently and temporarily fixed before concrete pouring, and then removed after the concrete is poured, thus simplifying and accelerating the construction process for the pre-embedded bolts.

[0011] Therefore, by relying on the positioning frame to fix the pre-embedded bolts as a whole, the efficiency of the pre-embedded bolt installation process of the steel pad plate of the track is improved.

[0012] The longitudinal component and the connector may be made of steel pipe or flat steel.

[0013] The pre-embedded bolts can be fixed to the positioning holes by means of nuts, or by means of cable ties, wire, or spot welding.

[0014] The top of the fixing frame is connected to the positioning frame body, and the connection method can be spot welding, clamping, snap-fitting, or binding. The bottom of the fixing frame is used to connect to the reinforcing bars of the track groove, and the connection method can be welding or binding. The fixing frame can be made of reinforcing bars, steel pipes, or plastic rods, etc.

[0015] Preferably, the fixing frame includes a first crossbar, a second crossbar, and a vertical post. The two ends of the first crossbar are located on the top surfaces of two adjacent longitudinal components, and the two ends of the second crossbar are located on the bottom surfaces of two adjacent longitudinal components. The first and second crossbars are connected by the vertical post, which can be connected to the reinforcing steel of the track groove. This design utilizes the first and second crossbars, located above and below respectively, to clamp the longitudinal components in the middle, thereby achieving a clamping connection of the positioning frame. Simultaneously, the first and second crossbars are connected to the reinforcing steel of the track groove via the vertical post, thus fixing the position of the positioning frame. In this design, the positioning frame is a reusable part, while the fixing frame is a disposable consumable, which can be destructively removed during disassembly. This facilitates subsequent disassembly of the positioning frame, effectively reducing damage during disassembly and thus increasing the reusability of the positioning frame.

[0016] The first horizontal bar, the second horizontal bar, and the upright can be made of steel bars, steel strips, or angle steel.

[0017] The connection between the first crossbar and the second crossbar and the upright can be a binding connection, a welding connection, or a threaded sleeve connection.

[0018] Preferably, the top surface of the longitudinal component is provided with a groove that matches the first crossbar, and the first crossbar is installed in the groove. Since the first crossbar is part of the fixing frame, this installation method can effectively prevent unnecessary relative displacement between the fixing frame and the longitudinal component, further enhancing the connection effect.

[0019] Preferably, the first crossbar, the second crossbar, and the upright are all ribbed steel bars with a diameter of 8mm-12mm. The ribbed steel bars have the advantage of being readily available locally, making full use of the leftover scraps after steel bar cutting and processing, thereby effectively reducing costs. Furthermore, the raised ribs on the surface of the ribbed steel bars increase the friction between the first and second crossbars and the longitudinal components, further enhancing the connection between the fixing frame and the longitudinal components.

[0020] Preferably, both the first and second crossbars are welded to the upright. Compared to binding and threaded sleeve connections, welding offers greater stability and flexibility.

[0021] Preferably, the number and position of the positioning holes on the positioning frame match the reserved screw holes on the multiple consecutively arranged steel pads. In this solution, since the positioning frame can accurately position the pre-embedded bolts of multiple steel pads at one time, the time for individual adjustment and verification is greatly reduced, thereby further improving the work efficiency on the construction site.

[0022] Preferably, both the longitudinal component and the connecting member are square steel pipes.

[0023] Preferably, the square steel tube has a cross-sectional side length of 40mm-60mm and a wall thickness of 2mm-4mm.

[0024] Preferably, the embedded bolt is connected to the positioning hole via a first nut and a second nut, with the first nut and the second nut located at opposite ends of the positioning hole. Compared to cable ties, wire connections, or spot welding, this solution using nut connections not only provides higher stability but also offers the advantage of easy disassembly. Furthermore, the nut connection method avoids the risk of damage to the embedded bolt during disassembly, as is possible with spot welding connections.

[0025] Preferably, a connector is provided every 500mm-800mm along the length of the longitudinal component.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. This utility model provides a positioning frame for pre-embedded bolts on the steel pad plate of a quay crane track. By relying on the positioning frame to fix the pre-embedded bolts as a whole, the efficiency of the pre-embedded bolt installation process on the steel pad plate of the track is improved.

[0052] Example 1

[0053] like Figure 1 and Figure 2 As shown, a positioning frame for pre-embedded bolts on the steel pad plate of a quay crane track includes a positioning frame body 1 and a fixing frame 2.

[0054] The positioning frame 1 includes multiple longitudinal components 102 arranged side by side and connectors 103. The multiple longitudinal components 102 are provided with positioning holes 101. The number and position of the positioning holes 101 match the number and position of the pre-reserved screw holes on the steel pad 8. The positioning holes 101 are used to pass through the pre-embedded bolts 3 and can be connected to the top of the pre-embedded bolts 3. The multiple longitudinal components 102 are connected to each other through connectors 103.

[0055] The fixing frame 2 is used to connect the positioning frame 1 to the steel bars of the track groove 6.

[0056] In an optional embodiment, the fixing frame 2 may include a first crossbar 201, a second crossbar 202, and a vertical post 203, such as Figure 5 As shown, the two ends of the first crossbar 201 are located on the top surfaces of the two longitudinal components 102, and the two ends of the second crossbar 202 are located on the bottom surfaces of the two longitudinal components 102. The first crossbar 201 and the second crossbar 202 are connected by a vertical rod 203, which can be connected to the reinforcing bars of the track groove 6. The specific connection method can be welding, using clamps, or binding. There are at least two fixing frames 2, and these fixing frames 2 are arranged sequentially along the length of the positioning frame 1.

[0057] In an optional embodiment, the top surface of the longitudinal component 102 may be provided with a groove that matches the first crossbar 201, and the first crossbar 201 is installed at the groove position. Specifically, the cross-sectional shape of the groove is semi-circular, and the diameter of the semi-circle is 8mm-12mm. The length direction of the groove is perpendicular to the length direction of the longitudinal component 102. A groove is provided every 0.5 meters to 1 meter along the length direction of the longitudinal component 102.

[0058] In an optional embodiment, the first horizontal bar 201, the second horizontal bar 202, and the vertical bar 203 can all be ribbed steel bars with a diameter of 8mm-12mm.

[0059] In an optional embodiment, both the first crossbar 201 and the second crossbar 202 can be connected to the upright 203 by welding.

[0060] Specifically, the lengths of the first horizontal bar 201 and the second horizontal bar 202 can be 400mm. The first horizontal bar 201 and the second horizontal bar 202 clamp the longitudinal component 102 from above and below, preventing the longitudinal component 102 from moving relative to the fixing frame 2, thereby fixing the positioning frame 1. Each fixing frame 2 includes two uprights 203, which are arranged vertically from left to right. The length of the uprights 203 can be 150mm. The top of the uprights 203 is welded to the first horizontal bar 201, and the uprights 203 are welded to the second horizontal bar 202 50mm from their tops. On the positioning frame 1, a fixing frame 2 can be installed every 1 to 2 meters along its length.

[0061] In an optional embodiment, the number and position of the positioning holes 101 on the positioning frame 1 can match the reserved screw holes on multiple consecutively arranged steel pads 8. For example, if the length of the steel pad 8 is 1200mm and the length of the positioning frame 1 is 3600mm, then the number and position of the positioning holes 101 on the positioning frame 1 can simultaneously match the reserved screw holes on three consecutively arranged steel pads 8. That is, the 3600mm long positioning frame 1 can be used simultaneously to fix the embedded bolts 3 of three steel pads 8. Specifically, the positioning frame 1 can also simultaneously match four, five, or six consecutively arranged steel pads 8.

[0062] In an optional embodiment, both the longitudinal component 102 and the connector 103 can be square steel pipes.

[0063] In an optional embodiment, the side length of the square steel tube can be 40mm-60mm, specifically 40mm, 45mm, 50mm, 55mm, or 60mm. The wall thickness of the square steel tube can be 2mm-4mm, specifically 2mm, 3mm, or 4mm.

[0064] In an optional embodiment, a connector 103 is provided every 500mm-800mm along the length direction of the longitudinal component 102, and the specific intervals can be 500mm, 550mm, 600mm, 650mm, 700mm, 750mm, or 800mm.

[0065] Specifically, there are two longitudinal components 102. Both the longitudinal components 102 and the connecting parts 103 are square steel tubes with a side length of 50mm and a wall thickness of 4mm. The material of the square steel tubes can be Q235B. The length direction of the connecting parts 103 is perpendicular to the length direction of the longitudinal components 102, and the bottom surfaces at both ends of the connecting parts 103 are welded to the top surfaces of the two longitudinal components 102 respectively. Positioning holes 101 penetrate the top and bottom surfaces of the longitudinal components 102. The size of the positioning holes 101 is the same as the size of the pre-drilled screw holes on the steel pad 8, and the positioning holes 101 are circular holes with a diameter of 26mm. The length of the connecting parts 103 is less than the width of the groove 7 of the track groove 6. Figure 4 As shown, specifically, the length of connector 103 can be 370mm.

[0066] like Figure 6As shown, the steel pad 8 used to place the rail 9 has a width of 380mm, and the center-to-center spacing of the screw holes in the width direction of the steel pad 8 is 320mm. The spacing between two adjacent screw holes in the length direction of the steel pad 8 is 600mm, 500mm, 470mm, and 450mm. The bottom of the pre-embedded bolt 3 can be provided with a hook to enhance the anchoring effect. The steel pad 8 is provided with a leveling bolt, which penetrates the top and bottom surfaces of the steel pad 8. The bottom end of the leveling bolt contacts and supports the concrete surface of the poured track groove 6. The function of the leveling bolt is to adjust the steel pad 8 horizontally. The leveling bolt is not shown in the figure.

[0067] Example 2

[0068] like Figure 3 As shown, a top view of the positioning frame 1 installed in the track groove 6 is presented.

[0069] This embodiment describes the method of using the positioning frame for pre-embedded bolts on the steel pad plate of a quay crane track as described in Embodiment 1, including the following steps:

[0070] S1: Fix the pre-embedded bolts 3 in the positioning holes 101 of the positioning frame 1. The pre-embedded ends of all the pre-embedded bolts 3 face downwards from the longitudinal component 102.

[0071] S2: Determine the position of the positioning frame 1 so that the planar position of the embedded bolts 3 meets the design requirements, and that the bottom surface of the positioning frame 1 is higher than the finished concrete surface of the track groove 6. The embedded ends of the embedded bolts 3 face downwards from the track groove 6. The positioning frame 1 can be placed manually or by crane. The distance between the bottom surface of the positioning frame 1 and the finished concrete surface of the track groove 6 can be 20mm-30mm, specifically 20mm, 22mm, 25mm, 28mm, or 30mm.

[0072] S3: Use the fixing frame 2 to connect and fix the positioning frame 1 to the reinforcing bars of the track groove 6. In the actual installation process, the fixing frame 2 can be connected to the positioning frame 1 first, and then the fixing frame 2 can be connected to the reinforcing bars of the track groove 6; or the fixing frame 2 can be connected to the reinforcing bars of the track groove 6 first, and then the positioning frame 1 can be connected to the fixing frame 2.

[0073] S4: Concrete pouring operation is carried out on track trough 6. After the concrete pouring is completed, the lower half of the pre-embedded bolt 3 will be embedded in the concrete, and the bottom of the fixing frame 2 will also be embedded in the concrete.

[0074] S5: After the concrete in the track groove 6 reaches the predetermined strength, remove the fixing frame 2, take down the positioning frame 1, and complete the construction of the pre-embedded bolts 3.

[0075] In an optional embodiment, step S1, fixing the pre-embedded bolt 3 in the positioning hole 101, may include the following steps:

[0076] S11: Tighten the first nut 5 from the top of the pre-embedded bolt 3 to the middle position of the pre-embedded bolt 3.

[0077] S12: Pass the top end of the pre-embedded bolt 3 through the positioning hole 101 so that the top end of the pre-embedded bolt 3 is higher than the upper surface of the longitudinal component 102.

[0078] S13: Tighten the second nut 4 to the top of the pre-embedded bolt 3.

[0079] like Figure 4 As shown. The first nut 5 and the second nut 4 are located on the upper and lower sides of the longitudinal component 102, respectively, and together clamp the longitudinal component 102, thereby fixing the pre-embedded bolt 3 in the positioning hole 101. In addition, the first nut 5 and the second nut 4 can also cover the exposed threaded part of the pre-embedded bolt 3, effectively preventing the thread from being contaminated by concrete, thereby reducing the amount of subsequent thread cleaning work.

[0080] By utilizing the threaded connection of the pre-embedded bolt 3 with the nut, the pre-embedded bolt 3 is temporarily fixed in the positioning hole 101. This fixing method is not only simple, convenient, and easy to operate, but also ensures high stability. Subsequently, the first nut 5 and the second nut 4 can also be easily removed and reused, saving costs.

[0081] In an optional implementation, step S2, determining the position of the positioning frame 1, may include the following steps:

[0082] S21: Determine the planar positions of the three pre-embedded bolts 3 on the positioning frame 1 using a total station. The positions of the pre-embedded bolts 3 are determined by measuring their relative positions to known reference points using a total station. The total station can measure the horizontal distance, horizontal angle, and vertical height of the pre-embedded bolts 3 relative to the reference points, thus enabling the positioning of the pre-embedded bolts 3.

[0083] S22: Determine the elevation of the positioning frame 1 using a theodolite. In this step, a level can also be used to check whether multiple longitudinal components 102 are on the same horizontal plane after adjusting the elevation, so that adjustments can be made in a timely manner.

[0084] In this scheme, the planar position of the three pre-embedded bolts 3 is determined by using a total station to define a plane, thereby determining the planar position of the positioning frame 1 and ensuring that the multiple longitudinal components 102 on the positioning frame 1 are also on the same horizontal plane. The specific position of the positioning frame 1 is determined using a total station and a theodolite, ensuring that its levelness and elevation meet the requirements. This method not only allows for rapid positioning but also significantly improves the accuracy of positioning compared to the traditional method of measuring with a tape measure.

[0085] In an optional embodiment, when the fixing frame 2 includes a first horizontal bar 201, a second horizontal bar 202, and a vertical bar 203, step S3, which connects and fixes the positioning frame 1 to the reinforcing bars of the track groove 6 through the fixing frame 2, may include the following steps:

[0086] S31: Insert the lower half of the upright 203 through the positioning frame 1 into the steel reinforcement area of ​​the track groove 6, and weld the lower half of the upright 203 to the steel reinforcement of the track groove 6.

[0087] S32: Make the two ends of the first crossbar 201 contact the top surfaces of the two adjacent longitudinal components 102 respectively, and then weld the top of the upright 203 to the first crossbar 201. Specifically, the two ends of the first crossbar 201 can be made to contact the top surfaces of the longitudinal components 102 first, and then the first crossbar 201 can be moved along the length of the longitudinal components 102 until the two ends of the first crossbar 201 contact the top of the upright 203, and then spot welding is performed at the contact position.

[0088] S33: Make the two ends of the second crossbar 202 contact the bottom surfaces of the two adjacent longitudinal components 102 respectively, and then weld the body of the upright 203 to the second crossbar 202. Specifically, the two ends of the second crossbar 202 can be made to contact the bottom surfaces of the longitudinal components 102 first, and then the second crossbar 202 can be moved along the length of the longitudinal components 102 until the two ends of the second crossbar 202 contact the body of the upright 203, and then spot welding is performed at the contact points.

[0089] In this scheme, the first crossbar 201 and the second crossbar 202 of the fixing frame 2 are placed above and below the longitudinal component 102 of the positioning frame 1, respectively, to clamp the longitudinal component 102. Then, the upright 203 of the fixing frame 2 is welded to the reinforcing steel in the track groove 6 to fix the entire positioning frame structure. This scheme avoids direct welding on the positioning frame 1, as direct welding may cause the positioning frame 1 to deform due to high temperature, thus affecting the positioning accuracy of the pre-embedded bolts. Furthermore, this indirect welding method facilitates the future disassembly of the positioning frame 1. If direct welding is used, the weld points need to be cut during disassembly, which may damage the positioning frame 1, reducing its reusability and hindering cost savings.

[0090] In an optional embodiment, step S5, the step of removing the fixing frame 2, may include: disconnecting the first horizontal bar 201 from the vertical bar 203 using a cutting machine or by hammering. Specifically, when the connection between the first horizontal bar 201 and the vertical bar 203 is a spot weld, a hammer can be used to break the spot weld. Alternatively, a handheld cutting machine can be used to directly cut the connection between the first horizontal bar 201 and the vertical bar 203. This solution can quickly disconnect the fixing frame 2 from the positioning frame 1, so as to quickly remove the positioning frame 1.

[0091] In an optional embodiment, step S4 may further include vibrating the concrete using a vibrating device. During the vibration process, the vibrating device must be at least 5cm away from the positioning frame 1 and the embedded bolts 3; the specific distance can be 5cm, 8cm, 10cm, or 15cm. The condition of each embedded bolt 3 is then checked. The checks include whether the embedded bolt 3 is loose from the positioning frame 1 and whether the planar position of the embedded bolt 3 has undergone necessary displacement. This can be done by assigning a dedicated person to check the condition of each embedded bolt 3. Specifically, the vibrating device may be an immersion vibrator, and the immersion vibrator specifically uses a vibrating rod to vibrate the concrete. Therefore, during the vibration process, the vibrating rod must be at least 5cm away from the positioning frame 1 and the embedded bolts 3.

[0092] If the vibration of the vibrating equipment directly acts on the positioning frame 1 or the pre-embedded bolts 3, it may cause the positioning frame 1 to shift, thereby changing the position or height of the pre-embedded bolts 3. Therefore, it is crucial to take measures to avoid direct contact between the vibrating equipment and the positioning frame 1 and the pre-embedded bolts 3. Simultaneously, the condition of each pre-embedded bolt 3 should be checked during the vibration process. If unnecessary displacement of the pre-embedded bolt 3 is found, it can be adjusted in time before the concrete hardens. This solution further improves the installation accuracy of the pre-embedded bolts 3.

[0093] In an optional implementation, step S6, removing the positioning frame 1, may specifically include the following steps:

[0094] Remove the second nut 4 from the pre-embedded bolt 3, then remove the positioning frame 1 from the track groove 6, and then remove the first nut 5 from the pre-embedded bolt 3. Use a cutting machine to cut off the exposed fixing frame 2.

[0095] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
