[0029] Referring to Figure 1 In the related art, the portal hoist mainly comprises a portal 10 and a lifting machine room 20, wherein the portal 10 is a main force structure, and the lifting machine room 20 is arranged above the portal 10. The portal 10 further comprises an upper structure 101 for bearing the lifting machine room 20 and a door leg 102 for transmitting force to a bottom concrete structure, and the two door legs 102 are respectively supported at both ends of the upper structure 101, wherein one of the door legs 102 is provided with a walking beam 30 near the upper structure 101, and one end of a rotary crane 40 is fixedly installed on the walking beam 30 to form a cantilever structure, and the cantilever end is used for hoisting a gate 50. As can be seen from the figure, the load of the portal 10 is mainly concentrated on the right door leg 102, and due to the unbalanced force on both sides, an overturning point is formed at the connection between the bottom of the right door leg 102 and the concrete structure, and the overturning moment generated by the gravity of the gate 50 causes a safety hazard to the stability of the overall structure of the portal hoist.

[0030] Referring to Figure 1 , Figure 2, A site is the anchor assembly 70 in the related art, by welding anchor support 701 outside the wheel frame 801 of the gantry hoist, when anchoring, anchor pin shaft 703 is inserted into anchor embedded part 702 through anchor support 701, the horizontal counterforce is provided by the limiting action of anchor embedded part 702 to anchor pin shaft 703, prevent the gantry hoist from slipping on dam surface 90, at the same time, it can also play the role of horizontal component force of resisting overturning moment, but ordinary anchor assembly 70 cannot provide vertical uplift resistance perpendicular to the horizontal plane, and the vertical component force of the overturning moment cannot be balanced by the structure itself. Additional counterweight is usually used to resist the overturning moment, which undoubtedly increases the wheel pressure of the wheel 80 and the load of the bottom hydraulic structure, which has an adverse effect on the service life of the related equipment and structure, and increases the economic cost.

[0031] In view of the problems existing in the above-mentioned related art, the utility model provides a gantry hoist anchoring device.

[0032] Referring to Figure 3 A gantry hoist anchoring device, comprising an anchor embedded part 1, an anchor seat 2, an anchor shaft 3, an uplift resistance assembly and a dam body 60, the anchor embedded part 1 is provided with a slot 121, the anchor seat 2 is provided with a shaft hole 21, the anchor shaft 3 is inserted into the slot 121 after passing through the shaft hole 21, the anchor seat 2 is used for connecting the main body of the gantry hoist, the uplift resistance assembly is coaxially fixed with the anchor shaft 3, the uplift resistance assembly is fixedly connected with the anchor seat 2 through the anchor shaft 3, and the end, away from the anchor shaft 3, of the uplift resistance assembly is embedded in the dam body 60.

[0033] Specifically, the uplift resistance assembly is added on the basis of the conventional anchoring device, the bottom end of the uplift resistance assembly is embedded into the dam body 60 structure, and the top end of the uplift resistance assembly is coaxially fixed with the anchor shaft 3, and the anchor shaft 3 is used to realize the fixed connection between the uplift resistance assembly and the anchor seat 2. Under the premise of not affecting the anti-sliding function of the anchoring device, the dam body 60 is glued and fixed with the uplift resistance assembly embedded therein in the process of gradually solidifying, so as to provide vertical uplift resistance perpendicular to the dam surface, so that the anchoring device can also provide anti-overturning moment for the gantry hoist, instead of the use of counterweight, thereby reducing the load of hoisting equipment and hydraulic structure, and saving economic cost.

[0034] In the embodiment, the anchor seat 2 is fixedly connected with the main body of the gantry hoist in the form of anchor bolt or welding. The anchor seat 2 horizontally overhangs outside the main body of the gantry hoist, the anchor seat 2 is preferably a box-shaped cross-section steel, the top wall and the bottom wall of the anchor seat 2 are parallel to the dam surface, which not only facilitates the installation and connection with the anchor shaft 3, but also effectively reduces the self-weight. The anchor shaft 3 is preferably a pin shaft, and the end face of the pin shaft abuts against the top wall of the anchor seat 2 to limit the anchor shaft 3. The slot 121 is clearance-fitted with the anchor shaft 3, and the size, shape and depth of the slot 121 are determined according to the anchor shaft 3.

[0035] Optionally, the anchoring shaft 3 has an axially penetrating receiving cavity 31 inside, and the pull-out resisting component is detachably installed in the receiving cavity 31. The end of the pull-out resisting component extends out of the receiving cavity 31 to be anchored to the dam body 60.

[0036] Specifically, since the pull-out resisting component mainly bears the axial pull-out force (Z-axis direction in the figure), the anchoring shaft 3 is designed as a hollow shaft, and the pull-out resisting component is detachably nested inside the anchoring shaft 3. This minimizes the projected area of ​​the pull-out resisting component in the XY plane, reducing its own weight by weakening its bending resistance, making the anchoring device more compact. The resistance to horizontal slippage is provided by the outer anchoring shaft 3, thus protecting the pull-out resisting component. The coaxially nested pull-out resisting component and the anchoring shaft 3 function independently, making full use of their structural advantages and avoiding disadvantages.

[0037] Furthermore, the detachable connection facilitates the separation of the pull-out resisting component from the anchoring shaft 3. In anchoring devices that do not require resistance to pull-out forces, removing the pull-out resisting component does not affect the original anti-slip function of the anchoring device. The installation of the pull-out resisting component can be selected based on actual usage requirements, thereby expanding the applicability of the anchoring device and avoiding resource waste.

[0038] Optionally, the anti-pull-out component includes a pre-embedded screw 4 and a connecting sleeve 5. The end of the connecting sleeve 5 is provided with a threaded hole 51. The pre-embedded screw 4 is threadedly connected to the connecting sleeve 5. The pre-embedded screw 4 is embedded in the dam body 60.

[0039] Specifically, the split-type pull-out resistant component is easier to pre-embed and assemble with the anchoring shaft 3. The threads on the outer peripheral wall of the pre-embedded screw 4 can provide sufficient pull-out resistance. The pull-out resistance that can be withstood can be controlled by adjusting the length of the pre-embedded screw 4. The pre-embedded screw 4 and the connecting sleeve 5 are purchased and used separately, which can reduce the production and processing difficulty of the pull-out resistant component. During construction, the bottom of the pre-embedded screw 4 can be inserted into the dam body 60 separately, and then the connecting sleeve 5 and the anchoring shaft 3 are installed in sequence.

[0040] Optionally, both ends of the connecting sleeve 5 are provided with threaded holes 51, and the pull-out resistant assembly also includes an extension screw 6 for connecting the anchoring shaft 3. The extension screw 6 and the pre-embedded screw 4 are respectively threaded to both ends of the connecting sleeve 5. The extension screw 6 extends out of the end face of the anchoring shaft 3, and the extension screw 6 and the anchoring shaft 3 are fixed by a locking nut 7.

[0041] Specifically, due to the small internal space of the accommodating cavity 31, it is difficult to connect and fix the connecting sleeve 5 and the anchoring shaft 3 from the inside, threaded holes 51 are arranged at both ends of the connecting sleeve 5, and a lengthening screw rod 6 is connected to the end of the connecting sleeve 5 away from the embedded screw rod 4, the lengthening screw rod 6 passes out of the end face of the anchoring shaft 3, and then is locked by a locking nut 7 from the outside of the anchoring shaft 3, which is more convenient for installation.

[0042] With reference to Figure 3 , Figure 4 Optionally, the anchoring embedded part 1 comprises a fixedly connected bottom plate 11 and a connecting cylinder 12, the insertion slot 121 is formed by the bottom plate 11 and the inner wall of the connecting cylinder 12, the bottom plate 11 is provided with a let-in hole 111, and the embedded screw rod 4 is arranged in the let-in hole 111.

[0043] Specifically, the connecting cylinder 12 is fixed vertically with the bottom plate 11, and the let-in hole 111 is arranged on the bottom plate 11 for the embedded screw rod 4 to pass through, so as to assemble the anchoring shaft 3.

[0044] In the embodiment, the projections of the bottom plate 11 and the connecting cylinder 12 in the X-Y plane are both circular and the centers of the circles coincide, and the let-in hole 111 is arranged at the center of the bottom plate 11.

[0045] With reference to Figure 3 , optionally, the dam body 60 is internally embedded with an embedded part 601, and the anchoring embedded part 1 further comprises an anchor bolt 13, which is welded and fixed with the embedded part 601 after passing through the bottom plate 11.

[0046] Specifically, the anchoring embedded part 1 made of steel is difficult to be effectively fixed with the structure of the dam body 60 after solidification, therefore, an embedded part 601 made of steel and the anchoring embedded part 1 is embedded in the dam body 60 poured with cementing material, and the top of the embedded part 601 is flush with the surface of the structure of the dam body 60; the anchor bolt 13 is arranged on the bottom plate 11 of the anchoring embedded part 1, and the tail end face of the anchor bolt 13 can be directly welded on the embedded part 601 in the process of installing the anchoring embedded part 1, so as to greatly improve the connection strength of the anchoring device and the dam body 60, and the existence of the embedded part 601 is equivalent to increasing the embedding depth of the anchoring embedded part 1 and improving the reliability of the anchoring device.

[0047] In the embodiment, the specific structure of the embedded part 601 is the same as that of the conventional concrete embedded part 601 in the prior art, and a plurality of steel bars are vertically welded on a square steel plate. A through hole is formed on the embedded part 601, and the bottom end of the embedded screw rod 4 is inserted into the concrete through the hole, so as to avoid position interference caused by the embedded screw rod 4 being too long and the embedded part 601. The through hole on the embedded part 601 can be an internally threaded hole, which facilitates threaded cooperation with the embedded screw rod 4 and further improves the fixing strength between the embedded screw rod 4 and the dam body 60. In other embodiments, the embedded part 601 and the embedded screw rod 4 can have no direct connection relationship, in which case the through hole on the embedded part 601 only plays a role of giving way; the embedded part 601 and the embedded screw rod 4 can also be fixed by welding.

[0048] With reference to Figure 3 , Figure 4 In the embodiment, four anchor bolts 13 are arranged on the bottom plate 11 of the anchoring embedded part 1, and are arranged in a ring shape around the center of the bottom plate 11. A wedge-shaped reinforcing plate 14 can be arranged between adjacent anchor bolts 13. The reinforcing plate 14 has two mutually perpendicular right-angle edges, and the two right-angle edges of the reinforcing plate 14 are perpendicular to the bottom plate 11 and the connecting cylinder 12, respectively. The reinforcing plate 14 has the effect of improving the bending stiffness of the connecting cylinder 12, and helps to improve the anti-sliding bearing capacity of the anchoring embedded part 1.

[0049] With reference to Figure 3 Optionally, the dam body 60 is a concrete structure, and the dam body 60 includes a first-stage structure 602 and a second-stage structure 603 which are poured in layers. The embedded part 601 is embedded in the first-stage structure 602, and the top surface of the embedded part 601 is flush with the top surface of the first-stage structure 602. The bottom of the embedded screw rod 4 is inserted into the first-stage structure 602, and the anchoring embedded part 1 is embedded in the second-stage structure 603.

[0050] Specifically, in order to achieve the anti-slippage of the anchoring shaft 3 and the anti-pulling of the embedded screw rod 4 in the anchoring device respectively, special installation methods are required. When pouring the dam body 60, two-stage pouring is adopted to form upper and lower layers of the dam body 60. First, the first-stage structure 602 is poured, and the embedded part 601 is embedded on the top of the first-stage structure 602 which has not yet solidified, and the bottom end of the embedded screw rod 4 is vertically inserted into the first-stage structure 602. Then, the first-stage structure 602 is cured until the concrete is hardened. Then, the anchoring embedded part 1 is sleeved on the outer periphery of the embedded screw rod 4 through the displacement hole 111 on the bottom plate 11, and then the anchoring bolt 13 of the anchoring embedded part 1 is welded and fixed with the embedded part 601. Then, the connecting sleeve 5 and the extension screw rod 6 are sequentially threadedly connected. Then, the anchoring shaft 3 is inserted into the insertion slot 121 of the anchoring embedded part 1 through the shaft hole 21 of the anchoring seat 2, and at the same time, the anchoring shaft 3 is locked and moved downward, and the anti-pulling assembly is integrally arranged in the containing cavity 31, and the top of the extension screw rod 6 protrudes out of the end surface of the anchoring shaft 3 through the port of the containing cavity 31. Then, the extension screw rod 6 is locked by the locking nut 7. Finally, the second-stage structure 603 of the dam body 60 is poured, and after the second-stage structure 603 is hardened, it is glued and fixed with the anchoring embedded part 1 and the embedded screw rod 4.

[0051] With reference to Figure 3 Optionally, the top end of the embedded screw rod 4 is lower than the top surface of the dam body 60.

[0052] Specifically, the top end of the embedded screw rod 4 is lower than the top surface of the dam body 60, which can avoid the interference of the embedded screw rod 4 protruding from the surface of the dam body 60 to the operation of the gantry-type hoist or other equipment. In this embodiment, the top end of the embedded screw rod 4 is slightly lower than the top surface of the second-stage structure 603 of the dam body 60.

[0053] Optionally, a gap 32 is arranged between the outer wall of the connecting sleeve 5 and the inner wall of the containing cavity 31 of the anchoring shaft 3, and the gap 32 is used for the free sliding of the connecting sleeve 5.

[0054] Specifically, the gap 32 between the outer wall of the connecting sleeve 5 and the inner wall of the containing cavity 31 of the anchoring shaft 3 can make the assembly and disassembly of the anchoring shaft 3 and the anti-pulling assembly more smooth, so as to avoid the blocking of the connecting sleeve 5 in the anchoring shaft 3.

When the anti-pulling assembly, the anchoring shaft 3, the anchoring embedded part 1 and the anchoring base 2 are assembled, the contact of the positioning detection switch 8 is in plug-in cooperation with the positioning groove, the contact of the positioning detection switch 8 is in contact with the inner wall of the positioning groove to turn on the control circuit, thereby feeding back the information that the anchoring device has been installed to the control center.

[0057] In the embodiment, the positioning detection switch 8 is a travel switch, the contact of the travel switch generates mechanical movement and is in plug-in cooperation with the positioning groove, thereby turning on the control circuit, converting the information that the anchoring shaft 3 has been installed into an electrical signal and transmitting the electrical signal to the control center.
