AI Technical Summary
In the flexible fixing system of crane tracks, the intimate fit between the embedded plate and the metal base plate leads to stress concentration, which easily causes damage to the embedded plate and the metal base plate. The fixing system cannot effectively adjust the height when the foundation settles, affecting the normal use of the crane.
A new embedded plate was designed, with a protrusion that is fully fitted with the track metal base plate on the upper surface, a corresponding recess on the lower surface, an internal thread insert is provided to adjust the height and flatness, and a slurry hole is provided at the protrusion to facilitate the filling of the mud.
Through tight fit, the stress concentration is reduced, the physical performance and durability of the embedded plate can be improved, and the track settlement can be effectively adjusted, ensuring the long-term normal use and safety of the crane.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of crane rail fixing systems and relates to an embedded plate used in a crane rail flexible fixing system. Background Art
[0002] At present, in the flexible track fixing system with adjustable crane track height, the embedded plate is made of a flat plate of PE material; in the adjustable flexible track fixing system, the upper part of the embedded plate is the metal base plate of the track. Since the bottom surface of the metal base plate is not flat but concave, the embedded plate and the metal base plate are not tightly fitted; when bearing the load of the crane, it will cause stress concentration on the metal base plate and the embedded plate. Since the embedded plate is made of PE material, the strength and elastic modulus are relatively low, and it is easy to cause damage to the embedded plate when bearing high-intensity loads, and even damage to the metal base plate; in addition, when the foundation under the crane track settles, the fixing system cannot adjust the height well. The above factors seriously affect the normal use of the crane.
[0003] In order to improve the stability of the flexible rail fixing system and adjust the height of the fixing system, a new embedded plate was designed to make up for some of the disadvantages of the original embedded plate and ensure the long-term normal use of the crane. Utility Model Content
[0004] The utility model is designed for a crane track flexible fixing system in order to improve the bearing capacity of a track fixing base, reduce damage to accessories of the flexible track fixing system, and adjust the height of the track fixing system.
[0005] The technical solution of this utility model:
[0006] An embedded plate used in a flexible fixing system for crane tracks, the upper surface of which is provided with a protrusion 4 that fits perfectly with the metal bottom plate of the track to avoid stress concentration, and the lower surface of which is provided with a recess 6 corresponding to the upper surface to ensure that the embedded plates are closely stacked, thereby being used to adjust the track foundation settlement; an internal thread insert 5 is provided inside the embedded plate, and the height and flatness of the embedded plate can be adjusted by bolts; an overflow hole 2 is provided at the protrusion 4 of the embedded plate to ensure that the lower space of the embedded plate can be completely filled with glue after the lower part is filled; and an embedded bolt hole 1 is provided on the embedded plate to achieve installation and fixation. Through the above solutions and measures, the various performances of the embedded plate are greatly improved, and the safety of the crane is ensured.
[0007] The material of the embedded plate is PA6 plus glass fiber reinforced material, which greatly improves the physical properties of the embedded plate.
[0008] The protrusion 4 is provided with a pressure plate bolt groove 3 .
[0009] Beneficial effects of the utility model:
[0010] (1) Excellent physical performance indicators:
[0011] The material of the embedded board is changed from PE to PA6 with glass fiber reinforcement. The physical properties of the embedded board, such as tensile and compressive strength and elastic modulus, are greatly improved, ensuring that the embedded board is stronger and more durable.
[0012] (2) Closely fit with the upper metal base plate to reduce stress concentration:
[0013] By adjusting the surface shape of the embedded plate to make it fit more closely with the lower surface of the metal base plate of the upper track, stress concentration is reduced, the damage rate of the embedded plate and the metal base plate is controlled, and the long-term normal use of the crane is ensured.
[0014] (3) Multiple layers of embedded plates can be used to adjust track settlement:
[0015] When the track foundation settles, you can use multiple embedded plates to stack and splice to adjust the track settlement. Due to the convex upper and concave lower design, the embedded plates can be tightly combined, adjusting the settlement height while ensuring stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical solution of the present invention clearer and more explicit, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0020] The utility model is an embedded plate used in a flexible fixing system of a crane track, which plays the role of positioning, leveling, transferring load and adjusting settlement in the flexible track fixing system.
[0021] like Figure 1 As shown, the embedded plate is a rectangular plate with 6 protrusions 4 on its upper surface, and the protrusions 4 correspond to the rail base of the fixing system, so that the embedded plate and the rail base are tightly combined; at the same time, overflow holes 2 are provided at the protrusions 4, which are convenient for gas discharge when the lower part of the embedded plate is poured with glue, so that the glue overflows and the filling degree of the glue is ensured; embedded bolt holes 1 are provided at one diagonal point, which are used for installation and connection of the entire rail fixing system; internal thread inserts 5 are provided at the other diagonal point, and the embedded plate is leveled by adjusting the screw to ensure the flatness of the embedded plate; the pressure plate bolt groove 3 facilitates the installation of the upper pressure plate bolts.
[0022] like Figure 2 As shown, corresponding to the protrusions 4 on the upper surface, the back of the embedded plate is provided with corresponding recesses 6, so as to facilitate the overlapping and combining of the two embedded plates; at the same time, when the lower part is poured with the glue, it can be closely combined with the glue.
[0023] This embedded plate has good physical properties and can fit tightly with the track base of the fixing system. It also has the function of adjusting the track settlement, which can well ensure the safe use of the entire fixing system.
[0024] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
